Where to lose my virginity

Ok sooo, me and my bf are both virgins. I'm his 2nd gf and he's my 1st bf. We've been doing more and more things lately and we've talked about having sex A LOT and I think we are gonna be ready to take the next step buuuttt where? If we do it I don't really wanna get caught and he gets really paranoid and scared when there is people around. Have any ideas? Btw we both live with our parents and are 18 and 17 and have been dating for a while
