Is it normal that i like licking my gfs feet?

As a bit of a background, I always was grossed out by feet and the thought of having one near my face was enough to make me gag. However when me and my current GF met in 2019, a huge change was coming in my future. Early last year, she had taken her socks off after a run and neatly folded them on the desk in our room. (She was going to wash them later, but didn’t want to go to the basement right then.) I mistook them as clean and picked them up to put them away and noticed a smell, a really good but strong smell. I shouted down the stairs “Annalise, did you wash these with vinegar, they don’t smell like detergent.” She asked if I liked the smell and when I said yes, she started teasing me before finally explaining what was up. I, at first repulsed by what had just happened, took another smell, and she busted out laughing and then slammed me on to the bed and started putting her feet all over my face. I, surprisingly enough, enjoyed this and she said, “you should lick the sweat off of them.” I didn’t really know if I was ready and I opened my mouth to say something and she shoved her sweaty toes inside my mouth. They tasted amazing, like I can’t even describe how delicious they were. So I knew what I had to do, and started licking her toes, which turned into the top of her foot, and then to her sole, and then to her other foot. I, questioning what had just happened, found myself very turned on, and I guess she realized this. She leaned forward and said “so what happened to hating feet, scared I was going to make you my foot slave?” And me being the horribly submissive guy I am, looked at her and said “If being your foot slave means being slammed onto the bed and being pinned down by you and forced to lick your feet, sign me the hell up.” After this we made out aggressively and then went on with doing things, but I couldn’t stop thinking about it. I started smelling all of her shoes and dirty socks and she came back into the closet to put something away and found me on the floor, with my nose in her dirty sock. She busted out laughing again, and took her barefoot and stepped on my face and pushed me down with it, and then she just stood there, teasing me before I started licking again, causing her to laugh, lose her balance, and fall onto my chest, where we made out on the closet floor. This memory is forever ingrained in me and I now lick sweat off her feet and suck her toes and least once a week, is this normal?
