How do I lose my gay virginity? To an older man?

I'm almost 16, and I'm gay. I've been wanting to have with my familys nanny's boyfriend sooo bad (anyone have tips on that????? Please?) but since that probably won't happen, I've just been wanting to have really bad. But, not with people my age for some reason. I get turned on the most by butch non-gay seeming guys (like me) in their 20's (like the boyfriend). How do I do this, without it being like I'm having with a stranger? (I mean i'm not just gonna find a hottie at the beach and yell "let's **** now" haha). Help. Thanks.
