Maybe you could talk to your husband about how it feels unbalanced to you? And put forth that you are willing to keep doing the fetish thing but you don't want all your sexy time to be focused around it as it does not do for you what it does for him and that's not fair.

I find the key to dealing with fetishes is communication. Quite often in my experience the person is getting to explore their fetish for the first time sometimes goes a bit overboard in the beginning when they find a willing partner.

To be cheesy, it is like a kid with a new toy (no way comparing you to an object) that they always wanted. They just want to play with it and ignore their other just as beloved toys and don't want to share. The fetish is new and exciting and fulfilling! It is hard to not want it all the time! And there is that little bit of fear that someone will take it away and you won't get to play again.

But you have every right to be fulfilled sexually too and have what you want taken into consideration into your sexy times together. Maybe some reassurance to your husband that you still are all GGG for his fetish but you need him to be just as willing in return.
