Neither, put the shirt back on

You back away from the feminine outfits, opting to slip back into the discarded shirt. Even wearing the unisex garment your new breasts and curves are plainly apparent. Your reduced stature makes it seem more like a dress than ever, the hem ending just above your knees.

You look around the room and find the space has changed. The door out now has some sort of drain set into it, with a large statue of a naked man facing it. It reminds you of a urinal. As you investigate your suspicions seem to be confirmed. There's a small drawing on the door depicting a naked man with an arrow pointing from his dick into the drain.

The statue is the size of a tall man, ending at the torso. It has no arms or head, yet still towers over your shrunken body. Running your hands over the chiseled musculature of the stone fills you with a thrilling excitement, and causes the stone cock of the statue to begin to swell. You pull your hand away, afraid to continue.

You face the drain in the door and pull up your shirt-dress, angling what's left of your dick at the target. After that bottomless goblet of wine you feel quite ready to relieve yourself. You relax as you begin to urinate.

Except nothing comes out of your penis. Instead your bladder empties between your legs, flowing out of the gap where your balls used to be. Your urethra has moved, and now you're covered in your own pee.

You rush back to the bath, throwing your soiled shirt-dress to the floor as you sink into the tub to clean up. Your cheeks are flushed with embarrassment and shame. As the lukewarm water in the tub washes away the urine, it takes the last of your dick along with it. As you scrub yourself clean you can't help feeling your new anatomy. Between your legs you now have a pussy. Your dick is entirely gone.

As you leave the bath for a second time, you notice the shirt you'd been wearing has vanished. The only clothing you can see to wear are the two dresses from earlier. One is a floral sundress that leaves your shoulders bare, but with lovely ruffles about the skirt and a hem just below the knee. The second is a bandage dress: magenta and ending mid-thigh. Your body would really rock that one now.
