I agree with Webgoji, that therapy would be the best place to start. There is a lot of stigma that was put on you by your parents that you need to work through.

I will say that watching porn will also skew your idea of what sex between a loving couple will be like. Therapy could also help you understand what a real love relationship looks like including what to expect from it sexually, because it is quite different than it is on TV on in the movies.
