I lost my virginity at age 15 to the girl next door, who was also a virgin. It wasn't a very good experience for either one of us, and we were both stressed out afterwards about pregnancy. I didn't have sex again for years.
I haven't had sex in any cool places, because I don't like to rush things, so the only good place is home. A quickie in the elevator or on the desk at work or something like that is probably less fun than it sounds.
My favorite two positions are doggy-style (so we can both watch tv ) and her on top, so I can relax and enjoy the view and play with her breasts. Also, she is more likely to come when on top.
Good decisions come from experience. Experience comes from bad decisions.
