First time

Ok so I have a bit of a dilemma.

Me and my boyfriend have been dating for almost two years, and have dated in middle school for four months before getting back together again. So you could say we’ve had a history. Anyway, I’m about to turn 18 in three weeks, and we’ve been thinking about having sex a LOT. Both of us feel ready to do it, protected of course, but there’s one problem. My parents are SUPER strict Christian parents, and his parents are strict as well, but not as much as mine. So...we don’t know really if a safe place to do it without being afraid of getting caught. Neither of us have cars yet, so parking isn’t an option. Any ideas??????

(I’m kinda sorta desperate heh)
