Interesting post, i have never felt like that since i started punting 30 years at 19. I have no problems treating a WG as a sex object as that what they are and advertise as such.
Agreed, why should guilt come into it?
WGs advertise their sexual services for a price and you have the choice to buy or not.
You are using the service and they are taking your custom.
As a WG I'm being paid for sex and I expect the payment. That's the upfront deal.
If I was in a relationship and felt my partner only really wanted the sex part of it and didn't care for me then I would feel used as a sex object. I would end the relationship.
If you feel you're being used for money in your relationship, I suggest you man up and get out.
