Can boyfriends and girlfriends "sleep over"?
Isn't there a moral issue to having a girlfriend or boyfriend spend the night (two to three times a week) and sleeping on the same bed?
Yes, of course. There are the issues of compromising chastity, engaging in immodest behavior, putting oneself in the near occasion of sexual sin, and giving scandal to others. And that's just the beginning of the problems of such a practice.
