Flare bases on toys

I made my own anal plug (again), this time out of a highlighter and a washer instead of using a bar (I'm desperate for a fix, alright?) don't worry, I'll take precautions, stick a condom on it and all that jazz, (live and learn) but don't take any mind to it right now. I was wondering how much of a flare a toy must have to prevent it from getting lost down under in case of an "anal wink". I understand that the flare may be relative to the size of the toy, but I'm just very curious.

I think a couple of inches in diameter would be sufficient in most cases. Unless you have stretched your little butthole. Then you might need to re-think the size....... especially if you have a bad case of the "anal winks" 😉

I suggest that the flare should be more than you can wink. If the fattest toy you ever put in your ass is 2 inches, make the flare 2-1/2. When it comes to making toys, if you are up to the challenge, check out http://www.sextoyscientist.com/. Its not anything thrown together or quick, but that site pretty clearly details how to create toys w/ thermoplastic elastomers, and you can modify their instructions for making a pocket pussy to suit just about anything your holes desire.
