F 20 might be a cuckquean

I grew up in a culture where it’s been normalized for men to cheat as long as they come home to their wives. Men are allowed to get their needs and urges out, which was also my family and what I saw growing up. My boyfriend (M 27) is no different, when we met I was a virgin and be slowly trained me and turned me into the slut that I am today. We have sex at least once a day, and he gets a blow job from me at least once a day too. But, he still fucks other girls and doesn’t even try to hide it. He just tells me that it’s physical and he needs to get his needs out, and what’s important is he comes back to me and my pussy is his favorite. He does fuck me really really good, and I find it hot that he’s also making other girls feel so good. He tells me that I need to share, he has enough to give to me and other girls. I often think about him fucking other girls and rub my clit for hours. Something about it is just so hot, I often suck his dick hoping to taste another girl. I feel jealous but at the same time so turned on. He’s a good man and he does deserve tight pussy.
