Search Results: don''t enjoy sex

I am in a sexually monogomous casual relationship. I thought it was just sex but it has now been morphed into what feels like a traditional dating experience. She had 2 ex bfs that forced her to have sex against her will. she's hated exclusivity titles sense then.

We had sex on the second date. She slept at my place but we couldn't sleep with stuffy noses. The third date was her place. Second sex time. She said she couldn't sleep. Then we went on a 4th date. It was a non sex coffee date. The 5th date went to my place. It was the third time having sex. I came inside her for the first time. She couldnt sleep and left to go home at 230am. She said she couldn't sleep. Then kissed me goodbye twice and apologized.

Should I be concerned she can't sleep? Is it normal?

I asked her if she got home okay. A few minutes later she said she did and ".. again, im extremely sorry for leaving abruptly. Please dont take offense."

I told her I understood. She said, " Thanks for understanding. I still feel like a little bit of a jerk. Well it was fun hanging out with you! Enjoy the rest of your weekend!"

Should I be concerned?
