I would just not sleep with a man until you know him really well. A couple of months ago I met a man off the internet. We talked for 2 months. He was moving here from Chicago. We finally met and went on a date. He bought me flowers and took me to a nice restaurant. We then had drinks. I finally said its late I need to get to bed. The next day he called wanting to see me before he went back to Chicago. I wasn't feeling well. He kept pressuring me. I said NO! Never heard from him again. I'm pretty sure the more I think about it he might have been married. But it was easy to just get over him bc I didn't sleep with him.
I've decided I'm not sleeping with a man until I know him very, very well. It's been 4 yrs. I'm waiting for the right one. And not all men are just looking for sex. I guarantee that.
Good luck.
