.....and I Love how much BETTER they feel to ME even, than a regular one. Everything Feels very natural, like nothing is there at all. they're amazing.
and I have found they provide better overall coverage too.
One just has to be sure to use a little lube first in the vagina before inserting one, then use some more in the condom before THE insertion.

(i said Vagina) lol.
I've become quite proficient with the f/c insertion, so it's not cumbersome or awkward at all.....
and for me, they work in every position.
They are what I reach for FIRST....always. while I ask my partner if they've ever used one, etc etc etc.
I'm surprised at the number of clients that it's their first experience with them.
I have a few clients who have requested that I already have one in before they arrive.
and that's always kind of fun too.
I've taken it one step further to have the lube warmed up, and that has seemed to make the experience even more enjoyable. (I think that was mentioned on a YouTube video about "how to use them" ....so I thought, hey "why not"?)
so, even when I travel I bring a bottle warmer with me.
Rover, If I were to speculate, I think many ladies Do have them but only get them out if the client inquires about them.
If they don't have them and more of their clients ask about them, I would think they would be more apt to buy them
