Dear Abby: My boyfriend, "Doug" (24), and I (22) have been in a long-distance relationship for a year, but we were friends for a couple of years before that. I had never had a serious relationship before and lacked experience. Doug has not only been in two other long-term relationships, but has had sex with more than 15 women. One of them is an amateur porn actress.

I knew about this, but it didn't bother me until recently. Doug had a party, and while he was drunk he told one of his buddies – in front of me – that he should watch a certain porn film starring his ex-girlfriend. It made me feel awkward. The next day he apologized.

Of course, having learned her name, I couldn't help myself from searching for her on the Internet. Now I can't stop comparing myself to her, and I feel intimidated and frustrated.
