I don't understand why it's even an issue with anyone. Some guys seem to be obsessed with having some huge penis, others would rather it be as insignificant as possible so it doesn't attract attention. My feelings reside on the side of desire for insignificance, probably in alignment with other aspects of life in which I tend to desire less visibility. But I'm pretty average size I think. I'll just not be concerned about it, knowing that no one else cares either. If they do then they are not true naturists and therefore their opinion can be discarded.
First off, I hate the word small. I prefer to think of mine as "fun size".
Second, the issue isn't between your legs, it is between your ears. Modern society has decided that bigger is better. Dating sites have profiles that just want hung men or 8 inches minimum. Porn has warped our values into wanting big cocks and big breasts.
Lastly, you are more than just a penis. You are a person within a earth suit. People worth knowing will want to know the total person you are.
A friend wanted to visit a nudist group as part of his bucket list. I said I'd go with him for moral support since I didn't have much interest in it. And I was scared shitless to drop my drawers in front of other people. But it didn't matter. I was welcomed with open arms. My endowment wasn't an issue.
Get naked and leave you worries with you clothes.
By all means I belong in this discussion, just checkout my profile pictures. The first time I went to a resort I was worried for the entire 5 hour drive about my size. Will they laugh, or just snicker, or point. Nothing happened. I arrived, checked in and went to my room. Got out of my clothes and headed to the pool. On the way I met several people and none of them did anything other than make me feel welcome, and comfortable being naked. I had a great time and have been to several resorts now and never had anyone make any comments. The only negative comment I have ever received was on this site in a private chat, which didn't last very long.
I go to playalinda beach a lot and ran in to the same situation, there was a group of young girls sitting there in there swim suits commenting on everyone's bodies,they were giggling about small dick's and everything else ,me being not shy or ashamed of my body or the size of my dick I approached them and told if they want to judge everyone's naked body then they should get nude also so we can judge them ,why are you at a nude beach if your not nude like the rest of us,they left shortly after
What I found on our first visit to a nudist resort is the lack of clothes is a great equalizer. The only person that is going to care about your penis size is you. I know we saw all shapes and sizes of people, all ages from the very young to the very old. None of it mattered. The most uncomfortable feeling we had was during the tour while we were clothed and everyone else was naked.
Just like women are made to feel bad about normal bodies because of what they see on TV and advertising, men do as well. The norm is not a huge penis but an avg, You will be surprised to see how you 'measure up' when you aren't looking at porn but are seeing normal, everyday people.
