You can get an orgasm by masturbation, which is an excellent start.

I'm not an expert but here is my idea.

Can you get an orgasm when there is someone else in the house?

Can you get an orgasm when there is someone in the next room?

Can you get an orgasm when there is someone in the same room, silent and perhaps facing away?

You see the idea? Stick with what works and bring the other person closer one step at a time.
