when we saw this trend with shemale, the guys hadn't given their wives/girlfriends cards - they simply used their significant others' cards without permission. this came up a lot when we had some chargebacks, first. i talked to a lot of the guys and they admitted they used their wives/gf's cards - they had a variety of excuses but some just said they didn't want the site showing on their cards.

in most cases, the women read their credit card statements and charged back because they knew they hadn't made the charges and tended to call ccbill and find out what it was they were billed for. when asked, their husbands/bf's assured them that they would NEVER join such a site so the women believed the evil porn site had billed them for a subscription no one signed up for.

btw, the women i know - college students, checkers at the market, postal workers, mothers, even my own mom - tend to prefer muscle guys but we haven't had that many women's names appearing on the cards. maybe guys into twinks and shemales feel they have more to hide - and aren't smart about how they try to hide it
