[NSFW] If you could be the opposite gender for one day, what would you want to do that your current gender stops you from doing?

Are there things you’d really like to try in life that just aren’t quite right for your gender? Perhaps you could do them, but they would be embarrassing. Perhaps it’s just difficult to get society to allow such behavior given your gender. Maybe it’s something that gender controls, so that only one gender can do it.

If you could be the opposite gender for just one day, what novel (to you) thing or things would you definitely want to try before the fancy new coach turned back into an ordinary pumpkin? If you’d want to do things that are decidedly too blase for adult-only audiences, then you want the SFW version of this question.
