"It becomes much more difficult to objectively see each other's character traits" says Susanne Alexander, a relationship coach and author of Can We Dance? "Some couples then slide into engagement and marriage only to discover they have missed seeing major aspects of each other." While not every dating scenario that involves sex leads to marriage or even a serious relationship, couples do owe it to themselves to talk about where they see their relationship going and how sex might change the relationship -- before they get in bed together. The woman may assume sex implies a commitment; the man may not see it that way," Allen tells Web MD.
Having an honest conversation with yourself about sex is just as important as discussing it with your partner, experts say.
"I spoke with a young man in his early to mid-20s who told me that if he didn't have sex on the first or second night, he'd move on to the next person," she recalls."Every woman and man should know their boundaries before they start dating, and most of us don't," says Cheryl Mc Clary, Ph D, JD, professor of women's health at University of North Carolina-Asheville.
