If you don't find any of the larger sizes with studded grids etc, then I would check online. That's almost a guarantee.
Personally though, the pleasure mesh, studded, ribbed, shared sensation etc didn't really do anything for me when we tried them a few years ago. *shrug*
Depending on what store you get them from, the larger sizes may come in those forms, but I would definately check online if you can't find them.
Trojan Large is the largest condom available on the market -- and from what I understand from the abnormally-large brethren I know, it's also reasonably comfortable as far as condoms go.
Yes, it's bigger than the Trojan Magnum. They're shaped differently, however, and he might prefer one to the other.
too large for condoms
