Hey everyone, I'm actually asking a question about my girlfriend. I'll give as many details as possible (hopefully nothing too gross), and hope that somebody can give me some information.

Anyway, about a year and a half ago my girlfriend and I started dating. Great! Everything, including sex, was amazing. At the beginning of our relationship, we were having sex something like three to four times a day when we met. We were a long distance couple, meaning that we could only meet for about five days a month, but when we did meet, we were rabbits. She would even seek out sex with me, and considering this is a culture where women aren't supposed to do that, it meant a lot.

Last summer, we both took a trip together. As usual, we checked into the hotel, and started to get into it. I noticed that she was urging me to finish as fast as possible, so I stopped and asked what was wrong. She told me it felt weird. I stopped there and told her not to worry about it. That was kind of the point at which everything changed, and from then on, she started to avoid having sex with me.

This was almost a year ago. She has lost almost all desire for sex and insists that she's "not normal" and "sick." It's hard to get a straight answer out of her concerning this, and lately, her continual rejections of me have been causing some fights. I, being a typical insecure male, have even started blaming myself for this and thinking that she's cheating on me.

We have been having sex over the past year, but it's been rare. She says that she's "trying hard" for me, and that it doesn't feel good. I asked if she's been lying when she said it felt good, and she said "that's not it..." Lately we've been focusing on using a vibrator and oral sex, but she hates performing oral sex even more than having normal sex. She's even trying to say "If I have to give you oral sex I may always hate sex."

I don't know what to do. I look at this on paper and think that she's being ridiculous, but I want to believe her. Is there any reason in the world why sex could suddenly, out of nowhere, feel strange? She has some other weird feelings in her lower abdomen, ranging from pain to a tingling/fluttering sensation, showing that she really does have something going on up there, but I can't tell what.

The only other piece of information that may help you is before all of this started, she had a urinary tract infection. I don't know how relevant that is though.

Has anybody here ever experienced something similar?
