I feel you. I'm the same way. I just don't want it to end. My ex-girlfriend was like that after we had sex, she would complain about not being able to have sex for the next 3 days because she said it hurts. It's kinda funny, you hear all the talk and jokes about women not wanting a "Minute-man" but when there's a guy who can go all night they complain about soreness. What is that all about?
