Biologically everything is the same - men have dicks and women have vaginas and boobs - but everything else is completely different. Women get extremely wet and it is the equivalent of a guy getting a boner in this world.

Men are the emotional ones that can often have lots of attitude but are pretty petite and the cute ones, while women are the strong ones who try pickup lines on men and carry muscles easier.

Everything about their world is the same but it's like men and women have switched places. Women can be very demeaning to men sometimes, saying things like they don't know about cars or they got a good job because they had sex with someone.

Additionally, it's really easy for men to be called sluts for wearing clothing that would be normal for men in our world - like tight jeans that might show an outline or a tight shirt. They treat men's nipples like you would treat women's nipples in our world - always covered and considered perverted.

You wake up seeing posters for products that would usually be marketed to women like lingerie or cute hoodies. A woman approaches you, wondering why you looked passed out, and sees you in your jeans.
