Ruby, Lucky, thank you for your contributions - they're greatly appreciated!
I'd looked at that site that Lucky provided a link for, and noticed an entire category of unlubricated condoms at
http://www.condomdepot.com/product/catalog.cfm/nid/210 . I always figured that it'd be the lube that'd taste foul to a provider and not the condom itself, so these sounded ideal but then you'd have to switch to something lubricated for intercourse. Hmm.
So Skyns have one thumb up, and two votes for Crowns.
I'd love to hear input from the rest of you.
