This may sound wrong. But it is a fantasy of mine.

I want to go to a popular and busy nude beach one day. I know it will arouse me. I want to go to feel inferior to other people. I want to see all the young fit people flirting with each other and having fun. Maybe they see me alone and decide to have fun and tease me. The older lonely pathetic average looking woman they have seen perving on them. They tease me to the point they see me getting wet and running off to take care of myself. They follow and catch me and tell me they knew I would be doing that. They then watch and keep teasing and mocking me. Telling me this is what I deserve for being such an old perverted lady.

(This is just a fantasy.)
