My husband's fetishes are getting weirder

Married 4 years. 2 babies. In our 20's. Great sex life. Up to twice a day even with the kiddos. Both of us were virgins prior to marriage so we learned everything with each other. I have zero fetishes. He has... well... a lot.... I just want some feedback because i feel like theyre getting weirder and I dont mind, to an extent... I just want reassurance that its all normal i guess.

Right when we got married, his tongue fetish was obvious..He loved sucking on my tongue for long periods of time and then I started licking all over his face as foreplay. That was easy. And he loves when I send him pics of my tongue all the way out.

Later, he admitted it went as far as a spit fetish. He started by asking me to get my tongue super wet ands then lick his lips. Then to let spit drop in his mouth. A lot of it. Now I spit all over his face and then spread it around with my tongue. He loves it. Think its weird. But easy enough.

Soon after entered the foot fetish. Started giving him foot jobs. Not as easy. But learned that if he does the work, I love it cuz its a great replacmenrt if im too tired. He loves them in the morning. And sometimes we simply uses the bottoms of my feet as a pillow and falls asleep for the night like that.

All fairly normal guy stuff? Id say so. But the next 3 started getting a bit more odd...

3 years into our marriage now, he had me get on all fours then he spread my butt cheeks and kissed my butthole. That was not ok. I was super uncomfortable. He wants to do it more and Ive let him give me tiny kisses when Im really turned on, but thats all. Havnt let him lick yet...

Next came breastfeeding. I was just starting to wean my youngest when he said that he read online about couples who nurse... He said he wanted to try. I gave an emphatic NO for 6 months. Finally, I conceded. I hated it. He loved it. Let him do it like 3 more times then cut him off. A couple of months later, I just weaning and the weirdest thing happend. He was fingering me and i said, "suck my nipple" and brought his mouth down to my nipple. He was beside himself and for some reason the switch flipped and I LOVED it from that day forward. Though I still think its weird..

This last one did me in.. He asked if I would pee on him in the shower. Later he clarified hed like me to pee during intercoarse, and over him laying down, and while he eats me in the shower. Im open to the idea., but honestly this is getting weirder by the request....

Whats my husband doing? Is this going to keep getting weirder forever?? I just need feedback.... Please tell me its ok lol
