It would have to be a temporary thing or an activated thing, like ranma only water would not be a viable trigger, because seriously being a dude does kick arse at times.
It would basically be just for the sex which would only happen if I had a double (& so I can take the advice of everyone iv intentionally pissed of by literally fucking myself). Otherwise im cleaning up at the lesbian bars in the city.
I could'nt imagine it being anything different in particular because women are people too. You would just be you only with breasts & a little extra leg room downstairs, you would'nt feel any different...except wearing womens clothes, the menstral cramps, bleeding from the puss, having guys perve on you all the time, tampons, little upper body strength, pregnancy, the actual birth process, hormones, sitting down to piss etc. As I said, a being dude kicks arse at times.
