I had to stop you there. Men spend billions a year on prostitution in this country alone, much of which goes to abusive pimps and human traffickers. That's besides what men as a group spend every year in strip bars and drugs.
And it's women who lack discipline? Seriously?
Men have a primordial urge to have sex - and many have no other recourse than to wine and dine women (or pay for prostitutes) to satisfy that basic, urgent, instinctive drive.
Women, on the other hand, get to be "wined and dined." Women seek the attention of men chiefly because it strokes their egos - not because failing to do so every couple of days places them in a state of increasing physiological discomfort (as seminal vesicles become overloaded). Women who have no choice but to pay for sex are few and far between.
Under those circumstances, it's no feat for women to "exercise discipline." It's like praising millionaires for not sleeping under bridges, while lambasting poor people for eating fried dog.
As for your throwing "and drugs" in there: I have no statistics handy about differences in the rates of drug addiction and alcohol abuse between the sexes, but the general consensus is that women are just as inclined to "over-indulge" as men.
But back to sex: For every "Chad" or "Tyrone" out there who carelessly "sleeps around," there are three or four loose women who are willing to spread their legs for them. It is "accepted wisdom" (backed up, e.g., by anthropological studies) that, throughout history, a relatively small minority of men procreate, while nearly all females "get to" reproduce. Genetic tests have demonstrated that every individual alive today has about four times as many female ancestors as male ancestors. I leave it to you to ponder the ramifications of that fact.
Regards,
Men earn more than women. Women spend more than men. Draw your own conclusions.
