Yes exactly. I dont know why this is still debatable. Trans women that transition to "men" have written about how intense their sex drive was after that first dose of hormonal (testosterone) treatment was. One said that she found herself just staring at womans butts on the subway and did not know why lol.
Older women on HRT ( hormonal replacement therapy) have said the same thing. One women on camera basically said she understands why men cheat. She said men are fighting a different battle. She also said that after the first doses of testosterone she caught herself checking out many more random guys. That never happened before. I can show you the video if you dont believe me.
Men are WAAAAYYYY hornier. If women were as horny as men nothing in this world would get done. Everyone would be having sex all the time even the ugly dudes would be having sex all the time with the hottest girls.
The story about checking out backsides on the subway reminds me of that time when a member on this forum (I forget who) said workplace policies against checking out/flirting with coworkers are stupid...Because such policies contradict human nature. It's human nature for a man to check a woman out, no matter how many rules a feminist HR director makes against it.
Horniness is a definitely a factor in why men cheat. There's more to it though. Since it's a lot harder for a man to get sex than for a woman to get sex, a lot of men feel like they aren't in a position to turn down sex. If a man is in a relationship, yet isn't getting sex from the woman, he'll likely take an affair if offered. I say this as a guy who cheated the very next day after I started dating a girl once.
Many a woman worships her vibrator. That's one key difference. For a woman, masturbation is often more enjoyable than sex (the opposite is true for men). Therefore, a lot of broads satisfy their sex drive through a vibrator (rather than sex)
