K so my boyfriend wants me to show him that I love him but I don't get how I can w/out taking it overboard

You must respect yourself and your body. Guys will say just about anything to get what they want. Your still very young and should really stand your ground and wait a while. If he really loves you he will respect your decision and if not well there are lots more were he came from.

He doesn't want sex from them to show him I love him he just wants me to show him how much I love him and I don't get what he means by that

Ask him what he expects. Obviously he's being a bit vague.
