One person diagnosed with anxiety is part of this 45% statistic that you mentioned. How many women of that 45% are only diagnosed with anxiety, and otherwise live normal lives? I'm betting for certain that you can't answer that, and it should be acknowledged.

Given that most of the sexlessness is coming from mate suppression tactics that are institutionalized at a societal level

Fucking lol

Sexlessness (and childlessness) also stems from the fact that people are living in a society that doesn't give a shit about them. Happy couples are opting not to have children because they can't afford it.

If men are agitated by not having sex, they can easily become the type of man that other women (or men) want to have sex with. Every single man (every single man) I've ever met who has had trouble getting sex has had tangible, fixable issues (well within reason, not like surgery or anything) that can help him significantly. I've yet to meet an exception.

You're blaming the wrong thing
