avoiding sex

There is no special word for it except plain old phobia or fear of intimacy. Get an appointment with a psychologist (counselor). After you have had a couple of sessions under your belt, tell you gf what he said and ask her if she wants out or to think it over and get back with her decision and you won't take offense.

You need to break it off. Be fair to her.

yes she is nice and she dont nag or tear me down

Is she nice to you? Does she nag you or tear you down all the time?

I think it must be her.. im very much into girls .. i love to eat pussy.. i love sex never had a problem with it before never said no.. have a few ex girl friends that could confirm that.. one of witch i ran into the other day.....

Either you aren't into her, aren't into girls, or aren't into sex. None of those are a bad thing, but if it is any of those, you may want to discuss it with her.
