I have been married for the last 4 yrs and I have hardly had any orgasm during the intercourse so far. I have always had to masturbate to have an orgasm. I srongly feel it is because of the shape of my partner's penis,which is facing downwards even when aroused, due to which he is unable to touch my G spot and hence I don't feel any pleasure. So I am losing all my interest regarding sex which is irritating my partner. He doesn't want to understand the problem. Kindly give some advise as to how to achive an orgasm and improve my libido.
