I think men need to do better. Like, just because sexual stimulation or desire may work differently in brains with more male hormones or more female hormones does not excuse the behavior. Whether or not a man would appreciate being shown a naked woman does not give that woman the right to expose herself without being asked. It is still a consent violation, whether the person thought the other person would like it or not. This is where education comes in about consent, sexual connection, and honestly just being respectful of other people.
I see what you are saying about the statistics, however in this case I do think a high percentage of men on dating apps are sending them. Maybe not 50% but certainly higher than the 2–4% related to mental illness. I will concede that the numbers need more data behind them, I think we are just delving in to research on this stuff.
Thanks for responding!
