For quite a while we offered a brand of condoms that had a special „potency ring“ that would in reality make it less likely to slip upward and ultimately off all the time.
This one is discontinued but we did replace it by 3 new ones from the same manufacturer:
El Toro
has the same „potency ring“ as the old model and should stay in place better compared to conventional condoms.
Good Timer
is coated with 5% Benzocain to make you last longer.
Big boy
Is an XL sized condom of 60mm x 195mm.
