My GF and I would like to try this simultaneously. She's always wanted a penis to fuck me with and I've always wanted to experience the power of her orgasms while I fuck her. We could have the same great sex, but different experiences! How great would that be! (Oh, and we'd want to have each other bodies!)
I'd experiment, find out how things feel, then probably go nuts in front of a mirror ;)
I'd enjoy the fun clothes and play with my tits all day!
I'd probably spend the day feeling on my female form to learn how to please my wife.
Give bad bjs.
Only joking ladies. Lol
Hopefully not be on my period.
This is a wonderful fantasy. I would first have to be sure that I could get back to my body because I came the the conclusion a long time ago that we girls won the lottery when it came to gender. However, I would love to feel what its like to be a man. I would love to know what it feels like to shave your chin, to be physically so much stronger, to be sexually attracted to women, and of course to have a cock that gets hard and to feel what a male orgasm feels like. After that I would want to escape back to being me with much relief
The one thing I would probably NOT do would be sleep - I'd want to have both male and female lovers and an orgy - but also some time out for the clothes!!
The curiosity about what it feels like to have an erection and use my cock would be satisfied.
Pee standing up, drink beer from a bottle while peeing standing up, hit on that girl at the bar that never gives me a second look, but always smiles great big for my hubby...find out if her rack is natural, and let her watch me pee standing up!
I would love to have one just for awhile, they are so amazing.
