Is this true?

True lugexd. But it in't just about making people look bad. The perception that those generalizations are absolutes can result in criminal activity being ignored or excused. And just on a person-by-person basis it can turn an otherwise reasonable person into an asshole.

I mean its kinda true since this could apply to most people. Sex is a big part of a relationship and men in comparison to women are more sexually active (for lack of a better word). And at the end of the day its the woman who decides whether she wants to have sex (cuz guys are almost always ready) I hope that makes sense

Guys are always ready? Some dudes think their dick speaks for every dick. Sex on demand gets old. I'm with a woman that has not even once said no and I'm the one that has to on the occasion, say no. Guys don't always want sex more, but on average this is true, more testosterone tends to equate to a higher libido. But, sex for sex sake is meaningless in my opinion. Sex should be about sharing and not being selfish. For instance, nothing gets me going like knowing how much my partner wants me and how much pleasure I bring them. I suppose there's an ounce of selfishness in that since I thrive off of their desire and pleasure, but it's not like a hit it and quit it thing... I could NEVER do that. Selfishness is in no way, shape or form a good indicator of a healthy relationship or for that matter, a healthy mindset. That's not to say I can't be selfish, but I know it's not right.
