Welcome to Gaia! ::

If you are not sexually interested in anyone and are not interested in any sexual activities, then I would call you asexual. If you're interested in learning more about different sexualities, look into Fluid.

However, if you are sexually attracted to people and are interested in sexual activities other than intercourse, that's different. In that case I would say you're a guy who just doesn't like intercourse.

Most guys like intercourse, but not all do. Same goes for oral sex. It's ok if you don't like every sexual activity. And of course it's possible that you would like it with different people or in a different situation (if you did orgasm, if you didn't get tired, if you didn't get friction burn, etc.)

If you don't experience a desire to have any sort of partnered sex or sexual attraction, then you may fall under the asexuality umbrella. AVEN's site may help answer your questions.

Like someone else said, though, it may simply be that you don't like that act. Worth a little soul-searching and experimentation (if you are comfortable), IMO.

It might help you to talk to self-identified asexuals. There's a guild on Gaia, and I hear AVEN's forums are filled with wonderful people. There is an asexuality support thread but I've lost track of it. D: Best of luck, mate.
