There is no such thing as a femcel. It is not possible for a woman to be an involuntary celibate. All women can get some man, somewhere, to fuck them. Might not be the best man, the most attractive, or the most superlative of anything; but she can find a man who will have sex with her. For women, sex is like water: abundant, everywhere, consistently safe, of adequate quality, free for the asking, and all she has to do is go up to someone and ask them to give her some.

Here's another thing: Women might devalue sex, but the fact of the matter is that sex is not nothing. Sex has intrinsic value and worth. If it had no value, women wouldn't have so much of it. Women have a lot of casual sex, so that must have some value too. At least women can get that. So it's not nothing. It has value, and women can get it.

There is no such thing as a woman in the "friendzone". Women do not get friendzoned. The "friendzone" happens only to men: He's attracted to her, but she keeps him around and gets him to do favors for her with her constantly dangling the possibility of sex. Women get fuckzoned. The man and woman are sexually attracted to each other, but she wants a "relationship" (allegedly) and he doesn't. So he keeps her around and gets her to fuck him with him constantly dangling the possibility of a relationship. (This sometimes happens with "fuckbuddies" and "friends with benefits" - eventually someone catches feelings and "wants more".)

Difference: In the friendzone, she gets what she wants, he does not. The man gets nothing he wants in the friendzone. He's doing all the work and getting no return at all. In the fuckzone, both the man and the woman are getting something they want - they're both getting sex. She's not getting something she wants (a relationship), but she is getting something (sex from an attractive man). She's getting sex from a man she's attracted to and that's NOT "nothing". So the fuckzone is qualitatively and quantitatively different from the friendzone.

There is no such thing as a "manwhore". There is no such thing as a man who is devalued because he's sexually promiscuous. If anything, he is praised and revered for his promiscuity. Women are actually more attracted to him precisely because he's had sex with a lot of women. The fact that he's had sex with a lot of women means he's sexually attractive, because only sexually attractive men can get a lot of women to fuck them. At the worst, women are indifferent to his promiscuity.

It's easy for a woman to be promiscuous. It's very difficult for a man to be promiscuous. A woman who can get a lot of men to fuck her is doing something any woman can do. A man who can get a lot of women to fuck him is doing something very, very few men can do.

Femcel, woman in the friendzone, manwhore - no such animals.
