Nudist + Dating event
You're looking for something rather difficult, and nudity is the least of it. You are better off meeting women in non-nudist environments, exploring other commonalities, and introducing the idea of nudism later, as part of who you are.
Several men, I don't have a number of how many, have had success in using the most popular dating sites. They were completely honest in all things and as one of their interests they put in "naturist". Most textile women had no idea what that really meant. After forming a solid relationship the gentlemen explained what that meant. If the relationship went nowhere there was no reason to explain the term. I understand that rather than being angry, most women were intrigued by the concept and wanted to know more. A few dropped the "perverts" immediately and some complained to the dating site. There was little the site could do for a guy being honest. Try it and keep us posted about what happens. There are also nudist dating sites but I haven't heard how effective they are.
P.S. I personally knew one gentleman who did this. The lady he met was a retired school teacher and had no knowledge of the subject. She eventually became a very avid nudist and they had many years as a nudist married couple visiting nudist resorts all over the world.
