I am part of a monogamous relationship. The only time we use condoms is when we're already post-coitus and we want seconds and we want to wait for absolutely no time, yet although we're already being risky, we don't need to be that risky. She's not a big fan of prophylactics, but we have one condom we agree upon and have in our war chest - The Inspiral

This condom is great for me because it has an enormous head to it. I don't know about anyone else, but I'm not a big fan of feeling suffocated. I've had other condoms that claim to have a loose head for a more natural feeling, which is simply not true. I don't know which latex human they've been sleeping with. But, the Inspiral does not make my penis feel claustrophobic, even if that does sound silly. It can breathe a little and with that bagginess, I can actually feel her move! There's nothing like feeling like sex when you're having sex. Unlike some other condoms, it doesn't feel like I'm getting a lap dance with a rubber band on my member. And the more I can feel it, the more I enjoy it. The more I enjoy it, the more I get into it. The more I get into it, the more she gets into it. The more she's into it, the more I can feel her and enjoy her. And the cycle continues.

We normally don't use condoms. I personally don't care for them. It just feels so... impersonal.
If I had to use one condom, it's the Inspiral. I love his cock inside me and all (it feels great), but his isn't rigged or have a spiral on it. Unlike other condoms, that make his cock feel like a simple dildo, I can feel him with this one.

The other condoms we've tried, while they help me stay not-a-mother, he just lasts way too long- and while I would normally have no problem with hours of sex, it just doesn't seem like he enjoys it and makes me feel like I'm doing something wrong. Normally we just throw it out (so much for protection) and go on and then the... umph! comes back.
Since we've used the Inspiral we have not experienced this problem. We both enjoy the entire time.
