Sex with my friend

My best friend and I were very horny curious young boys that started fooling around in grade school. First just jacking each other and spending a lot of time playing with each other and just being naked together.
After awhile we tried oral sex and loved it so we sucked on each other all the time and things got even better when we got old enough to cum and we began to swallow each others cum and figured out how to 69.
In the 7th grade I talked him in to fucking my ass one Saturday morning while my parents were gone and we were at my house alone for the day.
It was not that easy to get his dick in my ass at first and it was a little painful but once he started to fuck me it got really good really fast and he came in my ass and that was exciting for both of us so he fucked me several times that day and for years after that he and I had a lot of sex often.

How old is he
