Design flaw

After you finished putting on and examining your new outfit, the Grey doctor led you out of the medical bay into a well-lit hallway. As you headed down the hall, the clothing began to feel very uncomfortable in the crotch area. After each few steps you ended up pausing and reaching down to try to rearrange your junk, trying to prevent it from chafing so badly. Part of the problem was your transplanted cock. Unlike a normal human penis, the Gargo version didn't seem to shrink very much in its flaccid state. So even though it wasn't erect, you still had a hefty shaft of meat to stow. The other problem was that the suit seemed to have a very scratchy area in the crotch. At first, you tried moving your dick to the side, but with each few steps, it fell back toward the uncomfortable section. Next you tried moving it upward, but with no waist support built into the outfit, there was nothing to hold it there, and it just fell straight down after a few more steps. Then you tried squeezing it down one pant leg, and then the other, but the material in both was far to tight and pinched too much. Finally you tried readjusting the velcro-like connector in the crotch area.

Despite barely touching it, the fastener seemed to respond immediately to your motion, and it opened producing a 15 cm (6 inch) seam. Immediately, your frustrated cock slipped out and hung down through the opening. You were about to try to push it back in when you realized all the uncomfortable itching and chafing sensation was now gone. As your fingers felt along the fastener and inside the crotch area, you discovered that the texture in this area was very rough. You had two choices: suffer the unbearable scratchiness with your dick inside or let it all hang out.

Meanwhile, the Grey doctor had reached a door, opened it and entered a small circular room where he was waiting for you to join him.

"Will anyone on board be offended if I let it hang out like this?" you asked.

"The concept of modesty is not a concern here," the doctor explained. "After meeting other species, the futility of trying to impose your race's social conventions on other races quickly becomes apparent, and shortly afterward most races begin to realize many of their own conventions were effectively pointless to begin with."

That settles it. You're letting it all hang out.
