Interesting, you call me obtuse when it is you who reject logic and refuse to see what is in front of your eyes.
YOU see a man and decide against evidence that "no woman would want to be with him". YOU, not women since it is obvious that he has a girlfriend/wife. Instead of learning that plenty of normal men (who are not prejudiced) find partners everyday, YOU decide that it must be a fluke or exception.
BUT at the same time, YOU believe (not know or have data to back it up) that "every woman on earth" (regardless of age, looks, body shape and personality) can have a partner BUT, at the same time, that man that is with her doesn't mean a man partnered, but a man "shared" among many women who supposedly have no problem with that and, somehow, there are enough hours in a day for such man to have a high income (to attract them), go on dozens of dates, without the woman having issue for sharing and lack of attention. All this so other men could remain unpaired.
Well, you are right about that being a believe. A believe in a lie. As for no women making you feel right for having a partner, no wonder. After all, you are full of prejudices. Both when it comes to men, and women.
Well, keep ignoring what is in front of your eyes, data and logic. Maybe add a little question to the women that have a boyfriend: "do you share a boyfriend?" And see the reactions. And listen to the things they do with their boyfriends, then ask yourself, is there enough hours in the day for a man to do that 3, 4 times? 10? in order to supposedly have so many girlfriends. Won't they break up with him if he cheats? Your math is quite faulty. ;)
