This is ironic that you mention this.. I had a similar with my 4 year relationship with my now ex girlfriend. She always accused me of being a 'pillow queen' and being the bottom.. but she never initiated it, and as soon as I did whatever for her, she just stopped and that was it.

Like the above said.. it's all about communication. You just have to tell her.. like.. hey, look.. this really isn't working for me. Especially because you have been in a relationship for so long, it's really going to be hard for her to hear now. But you have to tell her honestly how you feel. If you're obviously having thoughts about having sex with someone that is going to respond to you better, there's a lack of communication between you and your girlfriend. I felt the same way. Both of us did, actually, and that's a big reason why our relationship ended. Both of us wanted to be with other people, because we were sick of the lack of communication, especially when it came to sex.

So catch it now before something negative comes out of it. Talk to her about it.
