he'd cease to be a friend. immediately. forever.
the mere suggestion that as his female friend i might lend him emotional support by giving him a convenient place to drain his nuts? fuck that noise.
i suggest he'd call up his closest male friend with the same request.
he needs relief? does the guy being hot really make a difference? being attractive wouldn't influence my reaction one bit. fucking. ew. in fact, anyone propositioning so would instantly become repulsive to me. as a human being.
if any part of you is flattered by being an easy cum dump, with no strings, seek professional help with your self esteem.
eta: i can't imagine any of my male friends valuing me so little as a friend.

not sure if i am pure "wtf" cranky... or shocked. my dudes just don't act like that.
