History of me:
I'm a male, 17 years old. History of sexual activity, little to none.
I think it's important to say that I figured out how to masturbate at the age of 12 and I never really stopped doing it. It was very frequent at most maybe 7-10 times a day but on average around 3-5.
I'm uncircumcised as well and I was unaware until recently of certain things you have to do to your foreskin and head if they are an issue. My foreskin is not entirely stretched out maybe 90%, so there is still pain and discomfort when I'm erect and I attempt to pull back the foreskin to entirely unsheath the head. Additionally, any kind of touch to the head of my penis is uncomfortable and in a way very slightly painful, like a stinging.
I never really abstained from masturbating so I thought of it as an addiction, because I really never stopped, it felt good.
I've chilled down from the whole 7-10 times a day and I'm around 3 now, and I've learned it's pretty common for guys to masturbate so it's not really an addiction.
I've always used porn to masturbate, and for awhile it seemed that it was most of what I looked at in day.
But recently my life went for a flip and my interaction with females became almost none, to actually quite a few. I know a lot about sexual acts and what they are, but I have no experience doing them.

The issue:
So this is the issue. I have a friend who has quite a bit more experience than me. She's had sex 3 or 4 times. Me and her have a very close friendship, we're best friends and we'd probably be going out if it wasn't for significant reasons that she couldn't. But irregardless to that, she wants to in a way "teach" me and try things out for not only her benefit but mine too because I've always wanted to learn. I am entirely attracted to her in every way, and I do have deep feelings for her, so to me there is no reason to say no! I'm not going to back down from a opportunity given like this.
