Q. I've been seeing a guy for four months. We agreed it would be casual sex and it was OK to see other people, but I've started to get jealous if he texts other girls. We hang out most days and are really good friends - I don't know what to do without ruining our friendship.

A. This isn't a friendship; it's a hot relationship. And it's getting hotter on your side. For many women, regular sex won't be casual; we can't always separate it from love. But love and sex make magic! You could tell him you're falling for him and risk him running scared. Or you could stop being on call for him. Let him miss you and chase you. If he doesn't? You'll find another guy for romance first with friendship to follow.
