Just a thought, since it's a gay bar and half the guys there are probably just wearing jockstraps anyways, why not wear the jock by itself? I think guys would be more likely to notice the 2 layers of underwear than they would the feel of the packer. Just an idea.
That being said, I've tried a lot of different packers and stp's and been to a lot of gay bars. The only one I ever had an issue with was the peecock gen2. Its really hard to pack with anyways, but it feels weird to the touch, especially through clothing. Mr. Limpy was my first packer and it still works great.
As for cleaning, be careful if you are wearing it inside dark colored underwear because mine got kinda stained over time. But I've heard if you wash it frequently that won't happen.
