Stronger condoms have been the bedrock of HIV prevention for many years, though the landscape has changed. Today, there’s a shift to choosing the right condom (which doesn’t necessarily need to be thicker) with good technique and plenty of lubricant.
In 2001, an evaluation found no evidence that thicker condoms offered better protection than standard condoms among gay men. The researchers also encouraged the appropriate use of additional lubricant.
Thicker condoms may lessen dick sensitivity, but there’s no evidence they offer better protection than standard condoms. And if your dick is so de-sensitised that you have to ferret around for hours before you can cum, what’s the point? On the other hand, guys often love a good ferret! It’s your choice: if you feel more comfortable and secure using a stronger and/or thicker condom, then use them!
