Damn, how did I not see this thread sooner!
I can relate so much... I was male, and at age 6-7 I was led into sexual intercourse with another male... Of all kinds..
The shitty thing is... I am wierd by sexual orientation.. realistically speaking, I'm heteroromantic, I love members of the opposite gender, and I have never kissed a guy. But, I was made to do many many things of sexual nature with him, then, and it sort of stayed with me...
I had this period when I was for some reason (which i still cannot explain to myself) seeking guys, for simply sex.. Luckily it lasted just a few months.
It, didn't go really well.
I am not sure what to think of myself. Especially for years, as gay people are often culturally alienated, and I was led into the abuse exactly by the friend-play.... Yep. I never told anyone who can legally do anything about it. I don't want anything to be legally done about it. It's shit. And just as confused as you are, maybe more.
