WOW have things ever changed and maybe not for the good. In my day, any woman having sex after a week was considered a slut...maybe a bit too harsh, but if you think about it, sex is very intimate and requires giving and sharing of oneself, physically and emotionally, and IMHO, not something to be taken lightly. I doubt you can really reach any level of intimacy after one week.
I think you knew this deep down and that was one of the reasons you could not perform. The crying about it, maybe a manifestation of "disappointment" in this choice of a partner? Sounds like she is a game player, so unless you are a "player" why stick with it. Move on and choose wiser next time.
Go ahead you all can call me OLD FASHIONED, I really don't care LOL
