Funny. Actually, it was absolutely free for her. I think a guy should pay for everything when he is dating a woman. Once your in a long committed relationship that changes a bit, but a woman should never pay when your dating.
Sometimes you just have a physical connection with someone. Her and I had it. It would be great because we would party (bars, clubs, house parties) until 2, home by 2:30 and then we couldn't keep our hands off each other until I had to leave for class at 7:30. My friends in class would bring me Gatorade and snacks because they knew I was having sex since 2:30 and drinking/partying for several hours before that. Good friends are hard to find.
