I was a bit taken aback when I first opened these. They aren't like normal condoms in any way. They do make a kind of rustling noise whilst in use - just turn the music up :) Unless being accompanied by a sound like someone unwrapping sandwiches is a turn-on for you. But despite the learning curve and the sound factor, the sensation is amazing. It's almost as good as the real thing. I've had partners check that it hadn't come off, and several times have pulled out to make sure that it hasn't come off. It hasn't - it just feels like it's not there any more.
One tip - bit of lube on the old boy before putting the condom on makes it much easier, especially for us more generously proportioned fellows. I know some folks worry that it will slip off inside - that's never happened to me, and I've used these things a lot.
