Interesting how people who do not know frequently give erroneous opinions. My GF and I found that the F2C female condoms work GREAT! It is the type on the market now. The previous type had some problems.
The F2C protects against STDs.
The F2C is large enough to make the largest guy (we had a guy who was 10 X 7 inches) feel like he was bareback. Just add a little lube inside the condom before it is inserted into her pussy. When a guy does me, we slip the female condom on his cock, lube up the outside real well, and slip it in me. Same way with her ass.
The friction is between the guy's cock and the inside of the condom, not the condom and the tender tissues of her pussy or ass, or my ass. That means we can be fucked for a very long time and NEVER get sore.
The F2C is much tougher than regular latex condoms. We have never had one break but had a lot of regular condoms break.
The F2C is quiet. (the previous version was noisy)
We have never had one get pushed inside either of us and some of the cocks have been very wide and very long.
We have not tried Penzoil because we use lubes that we are not allergic to.
The only problem with the female condoms is that they are hard to find. We buy ours from Amazon.com. We understand that there are a lot available free from health services, but because of the mis-information people have avoided them.
During the session that resulted in my photo album, Play with LPSG Member, after 45 minutes, the guy's cock broke the Magnum XL that he put on. You can see the size of his cock in the album. The condom was just stretched too tight. Her pussy was getting a little sore too. After a break, she put an F2C in her and they went at it again. It was the first time using a female condom and he loved it. Because the friction was between the condom and his cock, she did not feel any more soreness. She had fun with his cock pounding her for another 45 minutes before they decided to stop.
LPSG should make the F2C a feature for guys with large cocks!
