Limon - the situation is complicated by the power dynamics in society. Men (in general, in the sense of more likely to, obviously not all of them) are coming at this from a porn saturated position where they are expected to be pursuer, dominant, even enact acts of unwanted and unasked for sexual violence as part of "normal sex" (cf the many threads on here about women doing OLD and finding that the men they encounter now expect to be able to come on their faces or put hands round their throat on a first sexual encounter without actually asking first).
Women in general are not going into sexual encounters with the prior belief that they will be the ones passing judgement on their partner's suitability, expecting to dominate their partner, expecting to coerce their partner into unwanted sex acts. (See for example the BMJ survey into young people's attitudes to anal sex referenced in this article. For me the really chilling thing was that the young men pressuring their partners into anal sex applied that pressure while knowing that their partners did not want anal sex and would probably find it uncomfortable and painful).
In an ideal world both sexes would approach sex from a position of mutual respect. We do not live in that ideal world. Given the power imbalance, women don't actually need to be told to be nice, men do (unfortunately).
