Depends on how I'm approached, you know.

If you see it in the shower and you keep glancing at it hanging down between my legs, honestly, unless you make it grossly obvious that you're staring, I won't even notice. And I have had a couple of buds in my time who, while jerking with 'em, would make comments about my size. I like the attention and I don't really care.

And I've had to be that guy to answer the door in a pair of boxers or in a towel if I got a delivery in the morning. I just laugh, try to hold up my towel, and sign away. If the guy notices and says I'm bulging huge or something like that, I'd simply thank him. Now if he instantly dropped on all fours and begged for me to plow him... well... dude, that isn't my thing and that would be a little much.

Like I said, it's all in the approach. I don't mind casually discussing my size. And while I would be less likely to let some dude fondle my junk in the gym shower, if we were hanging out and having a couple of beers and he wanted to take a good look at it, I'd let him, sure.

It'd be even more fun if the guy himself were packing; always good to know your brothers-in-arms in the cock department.
