Why do guys not respect women on Tinder?
I've been single for some time and I have come to realize that most men don't respect the women they meet from Tinder. Or perhaps that's just my experience.
Let's say this guy John, who's 35, goes on a Tinder date with Kate, 25. He automatically feels that she owes him sex. But had John been introduced to Kate by his mate Philip (she's Philip's ex-coworker's sister's cousin), would he treat Kate the same way on the first date, by asking her to sleep with him straight away or the date is over?
Does it really matter how a man meets a woman, as men like to compartmentalize, like "all women from online apps for hookups, all women I've met in real life are for relationships? Or is that a myth?
