Thank you for the thoughtful reply, Lena! I would really like more people to know about them as an option for safer sex! When I first discovered them I found the FCs to be very intimating and awkward to use, but I think that's largely because I was NEVER taught anything about them. In fact, I received absinance-only sex ed in middle school.
It bums me out that they are expensive. Reproductive/sexual services and products should be free and available to everyone.
The best deal I have found was a bulk pack of 100 for 129$ online at condomdepot, so $1.29 a piece, which is totally useless if one can't afford to buy a giant bag of condoms. I do find that I typically go through less of them during a session than I would if I were using regular condoms. I usually only switch out the FC between pops, whereas with a regular condom I might switch out more often. Even so, I think it does end up costing more than using male condoms, which is a huge downside.
Also, they can be impossible to find in stores. I've never seen them at a drugstore, and have only found them in sex shops. I know where I can buy them in NOLA, but if I'm traveling, it's a huge pain to find them.
