We've been to 3 different nude beaches. All were while in port on a cruise ship.
Small beach, about 50 people, was crowded. Most were 60+ and you didn't want to see them naked, many were fat but not all. Most were couples but maybe 6 or 7 single old guys walking around looking at naked women. About 10 couples like us, relatively good looking, not fat. We always try to find others like us we can visit with. We did find and sit near a nice couple our age. It was nice just relaxing in the sun naked. The other wife was pleasent to look at, nice tits, hubby was cool too, way bigger dick than me.
Different time and beach, cruise ship in port. Large beach, probably over 100 people scattered all over. We went to an area with people closer together, we enjoy visiting. Asked a couple if we could sit near by, no prob. Many couples our age, many good looking(naked). A group of 5 gals about 30 sitting together, that attracted the creeps, old fay guys perving, no real problem tho. We visited with 2 other couples while we enjoyed the sun. Again its fun to be close to other naked people sometimes.
Different beach Jamaica. Small beach 50-60 people, most older overweight couples. A few like us. We found a cool couple to sit near and visit with. 3 different black guys(local?) walking around. All were Jamaican stereo type hung. One guy was huge his dick swung as he walked. They were obviously there to hook up. They would stop and chat with anyone/everyone including us. They were all polite. We'd watch as they tried to hit on a couple, some couples said get lost but others did engage in long conversations.
At every beach we saw several erections, FYI a fat old guy with a hard-on does not look sexy, an inshape trim male with an erection can be very attractive and I'm the husband. At two of the beaches while we're sitting with our friends me and other guy did get hard for a bit, more than once but nothing was said about it. Kinda funny how a guy(me) sees another guy's hard on and it gets me up.
Most of the people were shaved clean down there.
We did see several couples not too close to others with the wife playing with his dick or sucking it. Overweight people having sex isn't something I need to see.
We did have a relaxing time at each.
