I was hypersexual at the age of 4. 
For as long as I can remember which goes to about 4-5 ish years old. I was hypersexual and re-inacted inappropriate sexual behavior in private and forwards other people. I don't know how I became this way. It led to alot of masturbating, pornography addiction etc as I got older. I always felt guilty inside and wanted it to stop but couldn't. I didn't know how. I never told anyone because I was afraid I'd get in trouble. 
It wasn't until I was about 13-14 yrs old that I really had a mental breakdown about the whole thing. I felt like a fucking monster and was disgusted and dirty with myself. I didn't even like being hypersexual,  it was just like some addiction that I kept turning to hoping I'd feel better but it only got worse.  
I couldn't understand why I was this way or how I ended up like this. Why tf did a 4 yr old know about sex?! Why?!

I am now an adult. I have since lost complete interest in anything remotely sexual. I don't masturbate or anything. I've been "clean" for a few yrs now. 
However, I tend to get easily stressed at anything remotely sexual. I don't know why. This feeling started a little before I ended being hypersexual. I thought maybe it was because I had heard some SA stories and that's why I was stressed about sexual stuff now... But it's not going away. 
Something will remind me about Sex or sa and I'll fall apart. I'll be fearful and crying for hrs, days... I feel completely sick and like I've been violated or something. I relate to the same feelings expressed by others who've been sa. But I've never been sa or sexually abused at all. So wtf Is wrong with me? Why is this such a problem for me?
