Just because there is no sexual exclusivity within my life, that doesn't mean I get the other things from a relationship from off of a lady I spend an evening with.
I don't know about you, but imagine you suddenly won the lottery, you won an incredible amount of money (and this goes to everyone else reading this). Your husband says we can afford a chef now, you don't need to clean for me; is that cheating? Your husband says we can afford a cleaner now, you don't need to do any more housework; is that cheating? Your husband says that he is speaking with a therapist to help with his stress, so you don't need to be the barer of his inner demons any longer; is that cheating?
The answer to all of these is clearly no. So why would it be cheating if your husband had some sexual desires that required a woman who wasn't you, but paid for it?
Isn't it better he doesn't have a relationship with these other women, but uses their services instead?
When I go to Pattaya, I'm not looking for a relationship. When I go to Las Vegas, I'm not looking for a relationship. The relationship is my comfortable place to call home, but sometimes you just need to go out and play.
