So I am in an LDR with a girl who I've been with for 6 months and we had quite intense and close relationship. So today on skype she jokingly asks why I need her. Deciding not to be a complete dick and not to go with some whiny comment I say "to give her the best orgasm she ever had." And she says she is disappointed and expected me to say something short and witty.

It was 3 a.m. here, I am dead tired and don't really give a fuck about her reaction and brush it off. Nevertheless, she acts a bit pissed.

Anyway, any better ideas to handle this?
