You asked for situations where actions by both sexes are the same and men are held to a higher standard. Women have the battered women defense, what do men have? In those two situations, the laws are set up against men and not women. Hell, society chastises men who admit rape and DV. Men commit 85% of the REPORTED DV but the other acts are considered mutual combat or are not reported. Is that fair to men?
To your second paragraph, yes that is the problem and that could be the solution IMO. It won't happen overnight but as abortion has become rampant women have become a lot worse. I have anger at the impunity women operate with on a number of levels and we excuse it because of differences in pay or under the guise of equal rights and female power. Look at rape (where women lie all the time), DV (where men get arrested for mutual combat), and divorce (where men end up in financial ruin because of their wife).
Re: virginity. Men, as a majority, have never really valued virginity. To be a male virgin is a joke to other males. For women, it used to be something highly valued and now it is not. Society has seen the biggest change in women and their sexuality, not men. I don't hate women but I'm sick of hearing the excuses for women's behavior.
