I don't think it's as easy as "if you love your man, it doesn't matter." If you have no pleasure from intimacy, that will not work in the long run...no matter how much you love him. I think it's unrealistic to say, love will take care of it. I would look into videos, books, or other resources...for positions dealing with small genitals. Also, I would have him see a Dr.
Sex IS important. If you can't physically enjoy your partner, it will be a source of being unfulfilled and being frustrated. That's not good, in any relationship. If you love him, try absolutely everything you can, but don't feel bad about being disappointed. No-one should have to be unfulfilled by their partner. I would think the people that say love takes care of it, have never been in your position. To say that a woman's physical and intimate happiness doesn't matter, is silly, wrong..and incredibly harsh. If a man was completely unfulfilled, we'd be telling the woman to be careful, he will cheat, he will look elsewhere, it will harm your relationship. Why is it acceptable, for a woman to struggle with having pleasure. Does it matter less for her?
