Attitude taken towards sex by both males (who do the begging) and females (who can't be seen to want sex)
Derives from a Puritan belief that sex is wrong, dirty and a sin. Therefore society brainwashes men into thinking that sex is something that women need to be tricked into consenting to. Women are indoctrinated with the meme that all men are using trickery to get them into bed.
Also a reactive, defeatist and quick-fix attitude for men: "If I have sex with that woman, then my life will be better". If only guys (a category that I fall into) would understand that they will be much happier if they lose the trickery/sin attitude towards sex and replace it with one of cooperation with women towards love and mutual respect
The moral? Relax dudes! :-D
