I would hope that the man would wait, especially if it is developing into a serious, committed relationship that leads to marriage or long-term cohabitation.
Marriage is preferable -- I am quite conservative when it comes to sexual matters, having been raised by parents who were married 47 years prior to my father's death.
I've not had sex in a while, myself. Right now, I'm too bloody old to have sex for sex's sake. Besides, that's not how I was raised.
