Just think..................maybe you could start masterbating in front of a mirror and take the girl completely out of the equation...........you'd never need to date again.
It's normal man, like MrsPuddlesFL said, have sex in the bathroom and you will both, or all of you will find yourselves looking and starring. If you have mirror that fold outwards...prop her on the counter where the sinks are, lean her back and open the mirrors on either side of you and watch the magic in the mirrors!! My g/f and I love watching each other in mirrors or pics or videos for that matter
