What do you think is the point for many of those men online though?
So many of them behave so badly they aren't going to get a woman to have sex with them at all. The few that do manage to meet a real, live actual woman and have enough dates to have sex seem to end up ghosting/dumping her, and then its back to square one.
I have an ex who does this. I used to think the sun shone out of his backside but he dumped me twice and then dumped a woman I know twice as well, for no reason each time - the relationship was going really well and the sex life was great.
He just says he can't do relationships, but he really likes sex so that means he's turned into one of those awful men that shags around, and as he gets older, he's got less discriminate and I wouldn't go near him with a bargepole now. I would have to say his hobby is now actually internet dating but he has no intention of having a long term relationship. It must be such an effort to constantly be looking for his next conquest or thinking about getting rid of his current, a total emotional rollercoaster.
So I wonder what the point is - upsetting a succession of women, losing friends and risking his sexual health versus actually learning to appreciate the qualities of one person to maintain a relationship with - its not very logical, is it? I think he just lives in a perpetual state of avoidant confusion, making panicy decisions, as Peanutbutterjelly upthread points out.
