Also I've never "came" before like during sex
Is that bad?
And I don't really enjoy sex I just like the build up

Maybe you just haven't had a really good partner yet. From what you CAN feel during sex, does it feel good period?

Not really I don't get anything good out of it

I don't think there is anything physically wrong with you. I know lots of women that fake it because they can't feel anything.

Have you ever been given oral sex? That usually always causes an orgasm.
