I've just received my Flex order and I'm really impressed with the quality of the product. I'm not too worried about leakage as I don't bleed very much, just enough so that it's obvious on the condom. It's very comfortable, I can't tell that I'm wearing it.
However I can feel it with my finger, it's very obvious that it's a foreign object, unlike the sponge. And I have really short fingers so if a client fingered me he'd definitely know it was there. I'm not sure how it will feel during sex. I'm planning to take bookings today and say fingering is not allowed and just see what happens during sex. If a client mentions it I'll say I've got a diaphragm in for extra contraception. (Funny how some clients are practically phobic about periods but are all for any form of contraception, yet when I'm on my period I'm not fertile! Silly beggars!)
If a client does mention it then I'll go back to Beppy but use these Flex ones when I'm not working.
