Masturbation if fine, and healthy and bloody normal. I stumbled across it myself in the 80's with no external stimulus.
It's a good thing for the mind and body. A knowledge of oneself and ones sexuality. All good.
The idea that women should be degraded so some bloke can have a wank?
The idea that men's sexual satisfaction somehow trumps women's need just to be?
The algorithms that have constantly pushed a horribly perverted and violent idea of the sexual act?
Not OK.
I've spoken to my children about this, about the fact that I don't know anyone of my age that didn't find 'adult material' in a park or woodland.
So, there were always men that sought some kind of external stimulus, but it was shameful, that's why they hid it out of the house.
But, these were the men, that, when the Internet took wings, saw an opportunity to access material at home, they could hide it at home, on the computer!
Joy!
And these were the men that pushed and looked and when Internet porn was birthed, it was always going to be led by the kind if man that hid porn mags down the park.
The wrong 'uns.
The men that were Not OK.
And they are the ones that have been driving algorithms from the start. So we have reached a point where the Not OK blokes, the wrong 'uns, are now informing the sexuality of young men. It's a fucking mess to be sure.
My DS has a couple of MtF trans friends, both of them very lovely and sensitive young people. I do see their gender confusion as a rejection of masculinity as their fathers have it (both have dick-head dads), rather than a buring desire to be a woman.
