Advise please -paying for membership on adult sites

Hello,

Does anyone have any advice on safe and discreet ways to pay for membership on adult sites? I realize most sites bill with discrete names, but I am concerned about more than just that. I was going to buy a prepaid debit card, but it seems most of them require name, address, ss# to activate. My fear is that if I have a debit card out there tied to my name and ss# that it ties back to me.

Any advice out there? Thanks.
1) Money order by regular mail
2) Cash
3) You could always give the website your bank account routing number for them to withdraw the funds directly.
