How do I tell him this? Guys please answer?

make sure hes not in it for just the ,no matter how good it is it doesnt make up for how he treats you outside of the bedroom.if hes on the rebound and you tell him you want to make sure he wants to be your best friend and have a relationship steady with you and not for the it will save you a lot of heart ache and pain in the future.i wouldnt sleep with him until you find out what he wants and make sure he isnt in it for his self gratification to just get him through,i hope this helps,greg.
