Size issues

i think I'm average to big size wise but I've noticed some of the condoms from the shops seem to slip off or rustle a lot when they are on. Does anyone else experience this? I usually buy durex ones.

There are so many different sizes and models. Find one who fits you well and stick with it and you shouldn't have any problems :)

Look up TheyFit, they do condoms for small as well as hung guys. 100's of length/width combinations plus a bespoke service for anything else.
 
100's of length/width combinations

Almost, but not quite true. Their measuring kit has 100 possible length/width combinations, but they only sell 66 of those sizes -- they don't carry wide condoms for short dicks nor narrow condoms for wide ones.

You can find info and print your own fitting kit at TheyFit FitKit

It might be a good choice if they carry your exact size.
