if you are taboo about seeing an 'outsider' abt these problems google up techniques and also please discuss this with your partner. IT HELPS :)
Yeah I agree with charlietheman. And I also suggest you see a sex therapist if you want to improve your sex life.
there are many ways of enjoying sex besides clitorical stimulation. try finding you g spot and also try different sexual positions. oral sex(receptive) might help. work this out with your partner
