As soon as your mates see you hanging round with a girl that they know you're not sleeping with, the jokes start to fly that maybe don't actually like women any more in that way. She takes you shopping, you guys have quiet nights in, and you're so into her that you haven't had any notches on your bed post for a hell of a long time. It's not hard to see why they question it. Your mates find it hard to believe that while they spend their time out on the pull, you're with her even though you know it won't go anywhere. Sure, that might make rumours fly, but you're not doing anything wrong. If you choose to spend your time with someone you genuinely care about, then don't let any jibes stop you.
