It's an adult, real-life sex education class
We learn the difference between girls and boys at a pretty young age, and then in school, we learn exactly what those different parts are capable of when they get together. But when your sexual preference keeps you playing with the equipment that you have only, you may forget all those lessons you learned in sex education about what the opposite sex has to offer. These gay people decided to break that barrier and see what it’s like looking at the genitals of their homosexual gender opposites, and their reactions are pretty funny. Watch a gay guy and a lesbian show off their stuff to each other!
It’s for educational purposes, of course. They don’t have a lot of experience with the opposite sex, so they decided to plunge in and try it out.
