Your whole premise is the scarcity of sex, but you haven’t proven that scarcity, just states it as if it was a fact. But looking around shows that it is not true. Again, men can get plenty of sex by broadening the kind of partners they are willing to have sex with or simply by using masturbation, which is basically sex at will.

What they don’t have is sex at will with the person they want to. Their problem is not lack of sex which they can fulfill by masturbating. Their problem is that they want certain reactions from women which include things like being praised by those women, having homemade meals made for them, being served at home, being cared for, etc. And all that, by a woman of their choosing that also is expected to be fulfilled by doing all that for them.

Just read all the posts written by men who complain about how they should be appreciated for being men. You confuse the symptoms with the cause. It is not about sex, it is about not having as much control as they used to have/expected to have. Some people have trouble dealing with uncertainty and lash out against who they perceive as weaker. Just that.
