I've heard flesh lights are the (your word here) and a bag of chips. I've also seen ones modeled after...the anatomy of certain people. Usually porn stars. I don't know how accurate those are (or how the hell they would get a cast of a woman's vagina, tbqh...seems like that would hurt? :/), but they're there.
I don't know anything about how they feel...lol like I said, the "beach ball" notion is pretty pervasive.

But, I'm bored, and I'm heading home in about 2 hours to the joys of internet without content filters.

I'll see what I can find.
