It might be a little awkward the first time unless she has used them before. Insertion can be tricky, but use it as part of your foreplay to make it a little more fun They are non-latex, for those who might have a latex sensitivity or allergy (which is so not fun ) and as they warm up inside her body, they conform to her shape, so it is almost like going completely without. You might think it looks a little strange, because the open end does stay outside her vaginal opening, but it is kind of one more layer of protection as it cuts down even further on the potential for fluid exchange.

Good luck to you, hope  you find someone that uses them, they are fantastic !!

Next best thing to bbfs, and still playing safe.  If the escort has used them, it should be an easy transition for you to play. I've been with providers who can put an FC in themselves as quick as they can cover me.  
 

I've been with providers who've used them before. To me they're no better than a regular condom but certainly no worse. Maybe just not my cup of tea, but equally effective and from what I understand actually a little safer then a traditional hat
