Do you think I'm gay if I want to be taken away by an older guy?
Why do you want to do that if you're straight?
Because I'd really like to live that way
Sounds like maybe you aren't as straight as you thought you were. It's OK to be whoever you are if you're not hurting yourself or anyone else and you're all consenting adults.
Hell no, I don't want to be gay. I want to experience it for a few days, then go back.
That's OK, as long as everyone is onboard and legal. People sometime need to experiment with lifestyles. Later they may, or may not, discover it's not for them.
