Urinals are great places for checking out other guys. If a bloke next to me pees and then remains there cock out, he is interested in bonding! I like going into a urinals wearing just shorts and pulling them down to pee! Where is the shame in exposing my body?
As to troughs - best kind of urinals! You can climb in and get pissed on!!!
I've noticed that the comfort guys have to use open urinals depends a lot on the places/circumstances. Sports venues, concerts, some bars etc. where there is a line or alcohol involved, guys tend to care less but offices, restaurants, and so forth, they will pick a stall over an open urinal a lot. Also, some guys will only use a urinal if no guys are at the other ones.
Two of the funniest things are:
1. When there is a long line and open urinals with no dividers, the guys who wait just for a stall to open to piss.
2. When guys are using an open urinal, I've walked up and I guess they get pee shy; couple of times they zip up and go to a stall just to finish pissing which made me wonder why they used one in the first place.
The funniest was at a bar once when clearly everyone had been drinking too much (late in the night) and I walked up and had that moment when it takes a second to start pissing. Guess the guy next to me had the same deal and just laughed and said "I'll start when you start."
I too prefer urinals with no partitions. I used to visit the bathrooms on the beach and would go in for a pee. I always stood back a bit so I didn't get splashed on. I guess I am always a bit on show. I have seen many other guys look at me. If I catch them looking at my dick, I will generally peek over at theirs, and they mostly look away. No harm, you can either look or not look. Towels in the changing room are stupid. I used to go to a gym, and almost no one used towels except to dry off after shower. Showers were on an open bank with no curtails. I usually picked the one closest. Afterwards, the sauna was mostly towels on the lap. When i went in, I sat on my towel. After awhile, I noticed some of the other guys doing that too. When I go to our nude beach and am walking down the beach, I find it easy to talk to other nude guys there. It is easy to strike up a conversation, and yes, we do check out each others dicks, but that is ok.
Yes, I love to pee at open urinals with other guys. I like to stand back a little so I don't splash myself, so I am usually a little more exposed. I usually get looks. I just act like nothing is wrong and sometimes they pull back a little so I can get a glance at theirs. I went to a bathroom at the beach early one morning and had to pee really bad. They had two urinals side by side with no partitions and a sink right next to them, also with no partition. I walked in and there was a young dude washing his hands at the sink. I just went over to the urinal farthest away from him, pulled out my dick and started to pee. I stepped back a bit because it was coming out with such force. Suddenly I heard, Wow, dude. I looked over and he was looking right at my dick. I had just finished, shook my dick a couple of times, making sure I was still visible to him, then put it away and left. He was still looking at me as I left. I thought he would follow me out to talk, but he didn't.
