I haven't had the opportunity to try them, yet, but I have read a lot of comments from both providers and hobbyists that are overwhelmingly positive.  Might be fun to try them out with you!

Board for a current discussion.

The first is that the gal knows how to use them.   One time a brought some over for a gal who figured "How hard could it be?"  Oh, it be hard.   Be sure she knows how to install them, or "it" is going to get soft.

 
The second is that they can seem quite a bit on the cool side if you insert just after she does.    I suggest they be prepped in a glass of warm water just prior to use.

 
Use lots of lube in them, as well, warm lube that is.

 
And they can be very hard to find.   If you don't get them on line, you will probably have to go to a Planned Parenthood clinic to get them, which is what I did.   There is one down the street from me, but getting into one of those places is like going through TSA these days, unfortunately.

difficulty finishing in a standard condom. Using a FC feels like BB to a guy.

...they feel as close to BB as possible and while I like to be safe, I can't feel much with a regular condom.

It's good to know that these are catching on. Also, I didnt realize that they felt cold if not warmed up. I've had positive feedbaxk on the rare occasion I've used them, but also some dislike of them. and that could be because they felt cold.  
I just wish they were more readily available.

I didn't find it either great or bad. It did not feel like BB to me. Maybe it wasn't warm enough, I don't know.  Watching her insert it with a glass dildo was interesting.

What I liked about them is going between oral and intercourse felt more natural to me. I'd like to try that in a doubles session as an alternative to changing condoms every time I switch

One man said they were a visual turn off, but generally speaking when I had used them, they were a hit. I do think the times they were not they may have felt too cold.  

A glass dildo for insertion? Well, thats an interesting trick. LOL! Im still thinking about the mechanics of that one!

I love them..you are able to go from pussy to mouth and back again without fucking around with putting on and taking off condoms the whole session..

When requested. Honestly, i think they are little comical but they do work nicely.  Kind of sucks they are now prescribed.

Ive always found them a bit comical too. But then again, so are condoms. Necessary but they are both comical. FC strikes me as more comical, though.

What lube do you use when using FC? Regular water based one?

I have only used them with one woman. I really like them, despite how they look, because of how they feel. (BTW, she says they feel a lot better for her than condoms as well) Sometimes getting me in can be just a bit more tricky than with a condom, but once you're in it feels great, IMHO. I believe one of the keys is having a good amount of lube inside and out.

As to the cold comments; I have not experienced that, but this is quite literally one hot pussy we're talking about here. We finished up some DATY and I watched her put it in (which was fun to watch), as soon as it was in place so was I. I only remember thinking shit she's gonna burn me. No, that was NOT because of friction lol. Maybe the cold thing sort of varies depending on the people involved? You could always put it in and do a few minutes of BJ while it warms up I guess. Or DATO.

I have tried them...they  are great ,especially for a second pop..it's a mental thing knowing you are not wearing anything,.I would recommend having two or three for a date ,because sometimes you may need a change if you withdraw.

One lady I used to see,  would insert FC2 and i'd put condom on. That way I could go from greek to pussy and back, as often as we wanted. It was wonderful for a really long session.
As to the cold, grow a pair you wusses!

Female condoms

They are great in my opinion,  but sometimes it takes a lot of time to get them to fit right. Lol.  My advice is for the lady to be prepared beforehand....

They are great for duos.

 A lady can insert before you even visit so its 'warm' and ready. Push right out of the way to dine. While many wont want the FC in the way... you can easily dig in with it in her though.

I use them sometimes with fellas that have a tougher time with traditional condoms.

one lady who does.

I finally got to try one a couple weeks ago.  I think they are great, much needed in some circumstances.

I prefer my pussy without a trash bag hanging out of it.

I've always been curious to try it out, and I imagine it must feel good. But there's a stark contrast between look and feel because the opening would get in the way and ruin the view of her vulva, and as you know with us men, we tend to eat with your eyes first. It also depends on the position I have her in because although it would block my view in missionary, or cowgirl, or some other full frontal position, I rather doubt it would make much of a difference if I had her positioned in doggystyle. I imagine it would be the closest feeling to bareback while still using a condom because the responsibility doesn't fall on the man to apply his own rubber in this case. I really ought to encourage the next lady I'm with to try it sometime, but YMMV because not many females are comfortable using a female condom.
