Hi, really after some advice putting on Condoms properly. I've tried ANSELL Large 56mm and SKYN Regular (53mm) and the same behaviour happens in both I can unroll the condom about 80-90% of the way down but not all the way. I can force it further using all my fingers but then it just rolls back to where it was. Then from there any simulated in out movement and it starts to unroll back again. Length 15cm (5.9") girth around 12.5 (4.9"). Can you please offer any advice?
