Or an just an orgasm! I may be wrong but I think there are other ways of showing a girl that they want her for a gf then stripping down to one's boxer's (without any provocation) and trying to **** her before he's even taken her out one-on-one for a bit of non-sexual fun. Also known as an invitation or a date. O_o
Op: "Good friends" don't leave you or ignore you because you wouldn't screw them. (seems that's what he's done) Next time a "friend" that has never asked you out drops trow and does what he did.. don't go to bed with him and get him all worked up just to say "no" to him. Simply ask "what are you doing? And then wait for him to explain himself. Perhaps you can explain yourself as well (like how you like him but you're not ready for what he is attempting to make happen)
A guy can like you and even cuddle with you before getting down to business but it certainly doesn't mean that he wants anything more than to get bizzzy with you.
Back off from caring and trying to be with someone who supposedly likes you but won't have anything else to do with you now that you told him "no."
