I much prefer a FC to a traditional condom. I keep a supply and bring them with me when meeting a provider.
My frustration with them (no pun intended) is that it's a sensitive topic to discuss before meeting face to face and far too many providers I've seen either don't know about them and so are reluctant to trust them, or they have challenges using (inserting) them. Yes, it can distract from the mood, especially the 1st or 2nd time you try them. But that fades quickly.
The sensation for me is almost like going bare. And I suggest (with NO actual evidence) that it makes three-ways better as it can alleviate the need to deploy a new condom when switching... (again, I have NO actual evidence that that the risks of not switching with FC's are lower than not switching with traditional condoms. Maybe I just want that to be so...).
Thanks for asking about this! I really appreciate that a provider is taking a serious interest in this area. As others have mentioned, with age comes significant challenges to successful completion using traditional condoms.
PS: The solve to the problem of "hard to insert" is:
1. Take out the inner ring at the bottom. It's not needed and complicates the whole process.
2. Use a phallic shaped item (dildo, small vibrator, even a brush handle) to inset the FC. Leave a little material outside the labia to ensure the guy doesn't accidentally slip in outside the condom.
3. One of you should use your hand to guide the gent's entry. Don't rely on pelvic GPS to get you on target.
