Using sex as masturbation - similar to porn

I am doing my best to quit PMO, but do have a good sex life too. My wife is Japanese (we are close to divorce) zero sex - very similar many Japanese couples. I am black by the way.
However I see another Japanese woman with whom I have no real interest in but she is super hot, though sex feel like extended masturbation. I am thinking is just similar to PMO. I make her dress up cosplay and do role plays and I film it. (she gets really into it)

Do you think that similar to just porn ??

After sex I often masturbated to porn another 3-4 times before sleeping.

 

Better than porn but the brain doesn't see it like that. I feel like I need to cut certain type of sex.
