Men are a lot more welcoming, open minded and flexible when it comes to dating and dating apps. On dating apps, almost all the women want the same men and it's about the top 3% best ones. The rest of men get starved for attention, which is brutal to deal with.
Conversely, basically all the women on dating apps get attention. A lot of times, the average looking ones will get more attention than the prettiest ones because men won't even bother trying with them. That's also a reason why you see so many delusional women who have nothing going for them thinking they're 10/10 due to men pampering and showering them with affection.
Dating is tough for men. They're expected to make the first move and face rejection from the women who oftentimes have air tight, unreasonable standards-- especially online and on dating apps. This reality also will imply to most men in a relationahip and/or married that their woman settled for him but would rather have chosen a better man had she had the opportunity. Men will date women who are below the mans league, but women will not date a man who's not equal to or better than herself.
