I couldn't agree more with eaglepath! I have two problems: 1) a latex allergy and 2) a very thick penis. Besides "They Fit" and "Magnum XL" I never found a condom that was wide enough to wear comfortably.
The female condom is as sheer as a latex condom but, being urethane, isn't stretchy. It also does something that latex does not -- it warms to body temperature. I have YET to introduce the condom to a bottom who does not, at some point, ask me if it's really in him! There I have excellent hearing -- and I have never heard the "crinkling" sound that some nay-sayers have described. But then, my penis pretty much fills the condom, so there's not a lot of room left for it to crinkle...

For the top, it's the pleasure of bareback -- for the bottom it's the security of complete safety. This is URETHANE we're talking about -- it would take a KNIFE to puncture it.
The ONLY downside to the Female Condom is the price -- but, if you buy in bulk, it's not so bad.
There's a urethane condom in the UK that I'd like to try: It looks like a witch's hat and is slightly adhesive. The top place is over the penis and then twists it to shape. Sounds like a pretty good idea to me!
