1. Women cheat when they have options already lined up. I think I read about 80% of women who were studied that didn't feel the same for their partner anymore said they weren't going to cheat solely because they didn't have a man already lined up 2. Generally men cheat when they just want to have sex, but for women, it's generally the emotional attachment they're after. Cheating emotionally and physically hurts worse than cheating physically
These are generalizations from the results of studies, so of course they're not accurate 100% of the cases
I think it's equally looked down upon tbh, I'm bisexual and I would kick either one's ass hard before dumping them if I found out they had cheated on me. I would also make sure all our mutual aquaintances would know they cheated on me so they would resent and avoid them as well lol no mercy.
.. you're kidding right? In this day and age it's more or less drilled into us guys that if we don't beyond please a girl in every way possible, we will get cheated on and it will be all our fault.
Girls, on the other hand, are taught that cheating on your boyfriend/husband because you couldn't help being swept off your feet is romantic. You see that being encouraged all the damn time in all kinds of mediums and you'd be surprised at how many girls buy into it.
