You'll be fine. Sit back and watch or don't is always your choice. No one is gonna pressure you into anything.
We will be on our first cruise May 5th, SOLD OUT. It will be interesting to set back and see just how crazy it will be.
Both of us will be naked (Mrs. probably early than myself - it normally takes me a couple shots of Tequlia before I am LOL). It is a very freeing, refreshing feeling and like many have said - you really get used to seeing it so even as a guy it doesn't bother me much seeing another guy's "junk" hanging out.
Yes, there is nothing better than feeling the wind blowing around your balls as the warmth of the sun warms the rest! LOL!
