Are you about that? Of course there are many that is going to agree and even admit they pay for sex, but I believe Enoon has a bit of a point. Look at some of these two aspects.
You get free sex with someone you meet outside, or take to dinner or other reasons. You have unprotected sex, and make the woman pregnant. That, IMO, makes you a little bit responsible for your actions, as she could believe you have a crush or love her. On the other hand, if you pay for sex, and she let´s you have it your way, it´s more of her responsibility to protect herself from unwanted pregnancy as it is her occupation. Isn´t that a scenario that makes it easier to walk away without any thoughts?
You have sex with a girl without any cash transaction, there might be unwanted follow-ups, she might get your phone number or already had it. You might in a second of weakness feel obligated to give her a contact option. This is nothing that will be any obstacle when paying for sex, as she usually not want any contact info. Also not have to worry for any unwanted follow-ups.
That was only two small facts, that might make it a better option for some of us to go with the banking method.
