The only brand is FC2. You can buy them directly from the manufacturer for about $2 each.
https://fc2femalecondom.com. You have to choose the option that says you don't have insurance or your insurance won't pay because they are prescription only. They arrive by USPS. You can also get them on Ebay which can be a pain. Amazon also but very expensive.
You will have to buy them as the only girl I know that stocks them is SweetBabyBeth.
Not sold in retail drug stores. Cindie's used to carry them but I'd call first. Not hard to do DATY on the clit just move the ring out of the way. 80% of the time the girls want me to insert them which is part of the fun.
I usually put them in at the start and it takes me 20 seconds depending on how tight they are..Search on youtube for a demo video.
In my case they make me last longer.
The number one advantage is the girl is always ready in case you have to pause and reboot. You can go from penetration back to BBBJ often without having to rip off a condom. It's as close to the real thing as you will get unlike a tight cheap restricting condom They are much safer for the girls because they cover the contact area more. I've gotten zero pushback.
