Gawd......!!!!! Girls are pretty dumb, dumber than most guys in fact. For starters, you guys aren’t dating and don’t have any feelings for each other except for the fact that he loves your body and wants to sleep with you. Just so you know, if every guy gets to have sex with the girl he likes, you know what the girl gets called??? Right now only 2 words are on the top of my mind, one is a **** and the other one is a whore. Excuse the expression.
What exactly were you thinking when you entered this question? That guy wants to merely use you for pleasuring himself. And how can you be so naive saying I cannot loose my best friend and also cannot stand to see him dull, god what are you woman? Be mature and assess the situation on hand. Now if you give in to his puppy *** eyes, he would surely use you and might even act as your pimp. Here is what it looks like, ‘I want you to pleasure my friends so my name doesn’t get spoiled’; ‘I am in need of money so I need you to sleep with men so I could earn some’.
Get as far as you can from that pervert if you don’t want yourself being in an awkward position later on in your life. Befriend people with whom your value gets increased and not with the scum bag friend like yours who is degrading you. You might say, he has confessed at least, but if a guy gets to have sex after confessing, I’m sure there would be no rapes or sexual harassments in the entire world. Get away from him for your own saftey. And no, don't give in to his proposals and have sex with him, avoid him and threaten him that you would complaint to your parents or his parents if he approaches you again.
