Paying possibilities when one wants to join a members area of a ladyboy site

[Pollux]

A few times in the past I have joined the members area of a ladyboy site and to be a member
we all know that this must be done by credit card pay. Mostly via that billing company CCBill.
In the past I did so, but at the very risk of facing 'questions' from my close relatives when that monthly pay overview was received from my credit card company.
But for reasons of personal vulnerability (yes, personal, not standard), for me it is no longer wise to join membership via this way of payment.
O.K., those sites also offer a few other possibilities of billing but for me these are not real options.
One option of billing they do not offer: 'money transfer' paying with real money.
This can be done via a company 'Western Union transfer' (do not know if there are other companies also) and it can be done all over the world. Your personal vulnerability it then not at all at risk.
Why is this possibility not included as a way of payment. I have the feeling that using this way it would gain a lot more paying members and will benefit both that ladyboy site and the billing company.
Glad to read some forum members opinion and ideas concerning this matter.
