skyns original gets my vote with excellent heat retention.
Mates by Manix Original and ultra thin I also rate for fitment and doesn't smell as strong as other latex doms.
I always take my own doms and find thai's are fine with that; brazilians hit-n-miss. Roms don't usually allow and use their stinky
strawberry doms.
was checking the ladies pink site and came across this guide, which seems useful for fitment: according to that i'd be small-average
Pasante Trim - smallest
Any 'normal' Skins, e.g. Natural, Ultra Thin and Pasante Halo - small-average
Mates, most Durex (which I avoid as its the brand that splits most with me) - average
Skins Extra Large - average-large
Pasante King Size - large (this is the biggest standard condom easily available).
