You are not overreacting at all. It's completely fine to feel this way, as you have gone through something no one should.
As the above commenter said, just don't let it completely rule your life. But your son is still very young, so I would think that you shouldn't let him out of your sight anyway.
I'm sorry that had to happen to you.

I, too, was molested by a family member as a young child, and didn't say anything for years.  The really shameful thing to me was that I trusted this person, and I guess I just didn't realize what he was doing was wrong at first, but when I did he began to threaten me.  So much of my life has been affected by this incident, and it is only by the grace of God that I have been able to come to terms with it, and actually forgive my molester.

That being said, I still have a fear of this same thing happening to my child.  And you never know who might be the person that would do something like this.  My parents let my sister watch me, never thinking that she would leave me alone with my brother-in-law, or that he would do this to me.  So, I am very careful about whom I allow to watch my five year old son.  I feel a great burden, even now, to protect my child as much as I am able.  I stay at home with him, so he never needs to be with anyone else for very long.  I homeschool him so that he doesn't need to worry about any kind of violence at school (among other reasons).  But even then, I have to put a measure of trust in the Lord to protect him. 

I do not feel that you are being overprotective, so much as taking your burden and responsibility of motherhood very seriously, and not wanting the same pain that affected you to impact your child.  That is a very commendable care for your child. 

you shouldn't let htat stop you letting your child live his life to the fullest. just hope for the best and warn him. maybe he will be different then you.

*great big safe hugs* I don't have any advice. Just know that I'm sending your family good thoughts and vibes, prayers, too, if you'd like them.

@BrideofChrist21@xanga -  thank you so much its jus so hard and i trusted him so much and i loved him so much he was like my super hero he was 6yrs. older than me and like i said it wasnt jus me his sister and me and his younger aunt and now he has two little girls.

I understand your feelings and fears.
As others have said, I too was sexually abused as a child....and it wasn't even a repeated event.  But it truly messed me up.
I too, was very fearful of my children having the same thing happen to them.
A few years ago I started meeting with a mentor from my church.  She turned out to actually be a counselor and was able to really help me through so many of my issues. 
Working through my issues helped me to face life more like an adult rather than a woman that was still very much a scared and insecure child.  (Which is normal and understandable.) 
It also helped me to be able to think through the practical things like who will I leave my children with?  What are my standards for those that will stay with my children? 
For example, a couple of months ago I had a family friend who is a guy come and babysit for my children.  But, I have a rule that I will not leave my children with men (only) so this friend also had a female that we knew well enough come along with him.  I felt very comfortable having the two of them babysit together.  Before my husband and I left the house our guy friend was playing with my girls and they were tickling each other.  Although I completely trust this guy, I still took the time to tell him that I didn't want him playing with my girls that way because it's just one of my "across the board" rules...no guys tickling my children.  It sounds weird as I type it out, but really it is one of my ways of protecting them.
I hope this helps.  May God give you freedom from all that the abuse has brought into your life.  There is hope.

i completely concur.

Oh my god!  I was molested by my brother from the time I was five until I was about 14. Thank you for coming forward. It is good to know I am not alone. I am speechless that there is someone else.  Thank you, Thank you, Thank you.

I never told my parents. I let my mother die not knowing, I can't tell my father, it would break his heart.

I have kids, my oldest is fourteen.

Let me say first of all, your instincts are always correct, never question them. That being said, don't confuse  your fear for  instincts. Make it clear to your son that you will always believe him when it comes to this. I mean, the reason I never told my parents about what was going on with my brother, is because I didn't trust them to believe me.

You could get counciling if find you could trust someone that much. I don't. There was and is a lot of work on my part to find my own power, however. I still can't say I am ok.

Your son will be fine. Let him live his life. Trust yourself and build a bond with him throughout his life to let him know that when push comes to shove, you will always believe him and protect him. The truth is, as parents we can be watchful, but we can't stop it from happening if it is going to happen. I wish I could reassure you more than that.

It is a fact that a child molester is less likely to make a victim of a child that is confident, with a good head on their shoulders, with a child who is likely to tell. A child that is aware of their own self -worth is less appealing prey. Raise him fiesty and strong. It will help him in all sorts of ways.

Believe in your own power. With love, Angie

I was molested once by my aunt's husband when I was about 12. I never told my parents even when he was fired from his job at the school for suspicion of messing with kids and they asked me if he ever made me uncomfortable. I was afraid that my daddy would kill him and my daddy died never knowing (it was his sister's husband). I've never told my mother and probably never will. My sister knows...my husband and certainly my daughter. I told her about my experience and how I told my cousin who said she didn't believe me so I was afraid to tell anyone else. What I didn't realize at the time was that my cousin was his granddaughter and she probably suffered the same fate, only probably a lot more than I did. I told my daughter that if she didn't tell, I couldn't help her, just as my parents couldn't help me. I was lucky and was never around him again...I went out one door when he came in another at my grandmother's house...some aren't that lucky.

you are not overreacting. 

I am going through the exact same thought process at the moment.

For all the same reasons.

I think it is rational in regards to personal experience. It is hard to overcome that paranoia though. Very hard

It's ok, you have every right to feel that way. If we don't protect our children, who will, right? We're supposed to make sure they are safe, but at some point you'll need to move on from the past, for your own existence. You know in your heart that you need to find a way to get through the memories and move on, so you can live peacefully. I completely understand how you feel, I am trying to get past a traumatic time too. It's important for both you and your child, that you get some counseling, and believe me, it's worth it. You have been living with this pain for too long, you need to release it somehow and let it go so you can focus on other mommy stuff. It's better to work on it now, while your child is still very young, because eventually there will be play dates, school, and every day things to think about. The best thing you can do is clear the past and educate yourself on the signs of abuse, because even though children don't always tell their parents, they still show signs. When I found out that my daughter was being abused, it wasn't because she told me (she was too young to have any words for it), it was because she was acting strangely. We are still healing from it, even though it's been a few years since, and we've had some counseling. As a mother, I don't know what it's like to be abused, but I can say that it is extremely painful to find out. I am doing everything I can to set my children straight again and teach them right from wrong, because they still have issues. Having gone through counseling myself, I did learn how to determine if a child needs help, and I think that's a good start if you're afraid. Arm yourself and keep a watchful eye, and always know that you're one step ahead of the rest of us, because you are more aware.
