Oh I can wear a regular condom, I've had to do so in a pinch a couple of times. However, I fit most comfortably into a Magnum XL, and I've tried a few different kinds. Sex is supposed to be comfortable and enjoyable. I don't understand why it's a big deal if men like myself prefer, and fit confortably in (it's not loose at all, and the ring around the base doesn't hurt after five minutes) a larger sized condom.
I disagree with the OP and Faceking. Sex is all about preference, and while very few people cannot fit into a regular condom, many larger men PREFER to use a bigger one. I see no bull, no problems, and I sit comfortably at 8 1/2" x 6 1/4". Now, if a person is packing a 5" x 4" and using one, then you run the risk of pregnancy using a larger condom. However, if it's more enjoyable for a larger man to use a larger condom, fuck it, it's worth the extra investment...at least to me.
