That was my big plus for reality condoms - I can go through a box of Magnum XL things in an evening, and you're constantly taking one off, changing positions, doing something new, and then putting another one on (I didn't realize that this wasn't the norm, by the way, until someone pointed out that usually people use "a" condom for sex...) The reality you put in, and the inner anchor ring holds it in after you withdraw your cock. You can then have a nice deepthroat session, then go right back to fucking and it's all sparkly clean (tm).

The second problem with condoms other than Reality is that they pop. For me, about 1 out of 20-30 will pop. I never like finding this out after fucking someone for 10-15 minutes, pulling out and the "oops" moment, I just thought my partner was extra tight...

If you think Magnum XL's are tight, you should use 'off the shelf' condoms in Malaysia - I lived in Borneo (Sabah: Kota Kinabalu) for some time in the 80's and I couldn't fuck for a year. I got "one size fits all" condoms, and it was like trying to get toothpaste back in the tube...
