well why do you want/need a man at all?
most women fail on this point: you EXPECT a man to KNOW how to get you off WITHOUT telling/instructing/communicating with him to help you.
i expect my partner to educate me in the ways of her body, to ASSIST her in getting off. then, once i learn her and learn what she likes/needs, she doesn't need to communicate it to me so explicitly. as a man, i should pick-up on the lessons and do my job.
but to lay there and expect the man to just know. well, that would mean that all women are the same, and that's not true. some women like direct stimulation; some like indirect. some can only have clitoral orgasms, some can have vaginal.
teach & talk. let me know. then, lay back and enjoy.
btw, OP, this is an AWESOME question. lots of women expect guys to know their bodies while they refuse to talk about what they want/need.
