Why are so many "YOUNG PEOPLE" unhappy with the sex they are today?Why do they want to be "TREE FROGS","STOP SIGNS",Or OTHER ALPHABET SOUP.?

A very small percentage of people are transgender. It's not suddenly everyone is switching up. It's that it's a bit safer, sort of, to admit you are transgender and to do that publicly. Same thing with being gay. It's not that more people are turning gay because it's trendy, it's just that it's a bit more welcoming, sort of, to admit you are gay or an other. 

"Stop signs" that's amusing. The why is unknown. They must have a reason though.

It’s the easy access to the pörn industry that has been killing our sex drive and giving people unrealistic standards for sex. The best thing you can do for yourself is to stay away from pôrn.
