It could be, but I’m not sure women realize how MEN also react negatively to men who view porn or masturbate. It’s different, and I’m sure, nowhere near as profound; certainly not hurtful. But the truth is, most men totally disdain a porn lover or “wanker” and would never, in a million years, want either a man or a woman to know they do it. Why do you think there are so many disdainful terms men use for one who does it? I’m not sure I could even begin to count them all.
I was surprised, on reading “Charlotte Simmons” to realize how depraved many young people are now, in that way as well as in relationships between men and women. (Giving due regard for Tom Wolfe’s somewhat-exaggerated, derisive focus.)
But among even most young men, these particular sins are considered “unmanly” in a very major way. Most men are “outward” oriented in a very fundamental way. My own prejudice is that it is natural for men to be that way.
Not wishing to be too graphic here, sexuality is, among most men, considered “manly” ONLY when it is “outward” oriented; that is, oriented to a real, live, particular woman, and only to the woman as she really is. Resort to anything else is a demonstration that he’s not a “real” man. Real men have real women. There is an Italian saying about that, but I can’t say it here, or in mixed company anywhere.
I realize what I have said does not remove the hurt women feel. As a man, I will always remain defective in truly understanding that as a woman understands it. I would never even try to “advise” a woman how to bring “manliness” vs “unmanliness” to bear in a conflict like women have described in here. But it’s the truth, and a man who is into porn or masturbation knows it full well.
