IMHO, size and shape tend to matter more than thickness of material in terms of inhibiting sensation.

As long as I'm posting, please allow me to digress...

I used to work in a condom store in 1992-93, but even items with the same packaging are not necessarily the same today.

Pleasure Plus, for example used to actually fit me really nicely, but the fine print indicated they were not intended for anything
but vaginal penetration. Thus they were taken off the market after too many people didn't read the fine print.
When they were reintroduced many years later, they were a shadow of their former glory. Too narrow, and with too little
of the special feature to be of much benefit. If anything, they reminded me of a sideways variant of the standard reservoir tip
condom that usually makes me feel like the end of my unit is being squeezed...well... squeezed into the reservoir!

What surprised me most out of the assortment I brought when I went to visit my fiancee for the fourth time was the spiral tip condom.
It didn't fit or feel anything like I would have imagined. The fact that we both enjoyed the sensation so much more than we expected has
caused us to prioritize purchase of this condom.

Another surprise was the female condom. I had had pretty good experiences with this in the past, but they tend to be very expensive and also out of stock, due to the fact that the patent holder won't license the design to anyone else. It seemed to be working out pretty well again this time, but when my fiancee 'completed', the inner ring suddenly became extremely uncomfortable for her and we pulled the thing out right away. I would still suggest to other couples that they TRY it. Just don't buy a whole box right away if you can avoid it.
