Questions About Sex

Hello, I want to ask men if they have ever wanted to be women in sex, meaning not their partner, but their partner. If not why and if yes again why. To women: have you ever wanted to be a man in sex, the meaning is not you, but you them. If yes why and if not again why. And what do you think of the famous line: "If one key can open many locks, then this is the coolest key in the world, and if one lock can be opened by many keys, it is the most rotten lock in the world."? This question is for both men and women. Do you agree that if a boy has slept with many women she is the greatest dude in the world, and if a girl has slept with many men she is a light woman? Why and why not? I am a teenager and these things are interesting to me. I know my questions are very dumb, but I'm interested and I'll be happy if you share your opinion.
