I don't need a girlfriend, but I do want to have lovey-dovey sex. I want to go on lovey-dovey dates, but I don't want to be tied down. It's hard to find a relationship that's convenient like that. Karen gets jealous every time we meet, but I'm always doing it with other people. We like each other, but we haven't said we want to date, so it's an ambiguous relationship where we have raw sex and creampies. Is this a sex friend? Or a girlfriend?
