I actually have a story/character-description fragment based on this idea. P'raps I'll post it if anyone's interested.

I'd like to be able to change sex once in a while.

But, each time you do, you get a penalty during the next fight because of distraction. (Munchkin is awesome)

Hmmmmm....I would definitley change for the chance to watch sappy movies and be able to cry without feeling akward or being called a pussy.

I want to know what its like to get a period. Serious. I know it sucks but I want to understand completely.

I would also masturbate and have multiple orgasms. I want to know what a woman feels when she cums.

I also think I would be a pretty girl.....meow.

Ranma!
I would spend like two weeks just staring at myself and masturbating if I could turn into a woman. Then I would have a lot of wild lesbian sex. Oh sorry, did you say not to get raunchy? Couldn't help it.

Aside from that... eh, everyone has already mentioned all the non-raunchy stuff that I would do.

I might be curious to see how life is on the other side of the street as a woman ... I mean, not sexually (hmmm... lemme get back to you on that one), but to see what guys actually act like pigs... If someone's a complete bastard I'll just walk away and return as my pissed-off older brother ....

Also I'd use the female gender to talk my way out of parking tickets, to get preferential treatment for seating in public transport and to get free meals from workmates.

Or, if I was devious, I can use my other gender as a disguise to allow me to do all sorts of petty crime or mischief.
