There's a biological and social significance to why it is deemed that women may be less horny than men. Let's look at some of them:
Stud vs Slut
First of all there's this stud vs slut phenomenon. A guy who is known to get many chicks is considered by our society a stud. The chick who is known to get laid often is considered by the same society a slut. You can't win. It didn't used to be like that. In my previous lives I would fuck on every occasion, now you have to go through loops to get laid. Cause chicks are so hard to fuck nowadays. But is anyone surprised? The society forces them to act like they're nuns otherwise they get all those funny labels. We can especially thank our good friends religious prudes for centuries of brainwash that got embedded in our brains so deeply that women tend to say "NO" when you approach them and tell them you want to fuck them tonight. It's fucked up, really.
Women typically bear the responsibility of unwanted pregnancy more directly, than men. Many women realize that well and while men hardly take possibly pregnancy into account when theyíre horny, women still have that option at the back of their heads which makes them more hesitant to have a random fuck. That is just another reason why women get as horny as men, but they donít show it or hold back.
This may not be directly related, but most men will reach orgasm even during their First Time Sex where as many women donít reach orgasm even after years of fucking.
To sum it all up. When girls have sex, they realize the society may frown upon their decision to engage in the mighty fuck and this of their deed as ďdirtyĒ, the anxiety of getting pregnant lurks in the background and even if she gets passed those without issues, thereís still a good chance she wonít get off. So why the fuck bother, right?
So yeah, women get as horny as men, but men have social and biological advantages that allow them to follow up when they get horny. Girls have traditionally been formed to hold back. Hence they appear as less horny than men.
