Discreet dating websites
Find others who are looking for discreet relationships.
To avoid this from occurring and resulting in discovery of your action, consider signing up for a new credit card to pay for the adult dating service fee.
A new email account that is known only by you (and the people you meet on the adult dating website) can eliminate the possibility of your messages falling into the wrong hands.
You never know who in your home already knows your email password.
To further reduce the likelihood of the bill with the unusual charge appearing in your mailbox, obtain a post office box and use that as the mailing address for the credit card bills.
The post office box can also be used to send and receive correspondence from partners you may meet on the adult dating site.
