You should probably switch from omeprazole to famotidine. I used to be on omeprazole until my doc noted that there are indications of it be a carcinogen when used long term. Switching was a non-issue for me.
Of course, I’m just some rando on the internet. You may want to seek some reliable info on the topic. Look for PPI vs H2 receptor antagonist.
This doesn’t work.
If it were only about novelty, then why aren’t there more bellybutton fetishes?
Being a fetish-having person, I can tell you there there is more than just an attraction to the object of your desire. It is a primal, deep, uncontrollable NEED to see or touch the object.
I am not a foot fetishist, so I do not presume to know the intimate details of what they like, but I can promise you, it has nothing to do with novelty. Fetishes have so many variants also; there are foot fetishes, sock fetishes, feet squishing stuff, toenail paint things, some want a footjob, some want to lick them or suck on toes, some people like big feet, small feet, the list goes on and on.
Maybe read just a tiny bit? https://en.wikipedia.org/wiki/Sexual_fetishism#Cause
