I'll go with my hearing. The other two I use way too much.

Sight. Blind characters in fiction are usually OP to the point where they might as well not be blind anymore.

Being deaf would be too awkward since you have watch people forget you're deaf all the time. And lower boom is...precious to me.

Well... Uhm... I would like to be able to pee with my pee-nis, so I guess hearing? Sight last in any case.

Lose my penis.

May I offer my butthole as a possible tribute? I'll find some other way to excrete.

I was thinking this. Being deaf will cripple you for life. Not only your ability to work or study will be decimated, you will be disoriented and will largely impair the way you navigate and walk, AND it is unlikely you will be able to date easily while deaf anyway.

Penis of course.

The other 2 are important to your second by second enjoyment of the world.

If by penis you mean the pillar and the stones, then take my penis. I love my music more than my whores.

This. People are seriously underrating our ability to hear, you need it whole the time.

Penis easily, both hearing and sight affect almost every single aspect of your entire life.
