To sex or not to sex

I feel distant from sex. I feel i dont need sex. Been with my bf for 3+ years now and feel bad to deny him if sex when its clear its something he needs. But i feel its something i really dont. Were great together. However its recently come to me that i dont want sex or i want it extremely rarely. I dont want every close encounter to end up as sex. It doesnt feel like it should. I feel bad saying no. But also feel like i shouldnt.

Compromise? A possibility.

Do i want to compropise? I dont know. I would rather not. But i guess it depends on how much he needs from me.

What would you do?! What should i do😭

Iwould hate to break up over something like this. But it feels either unfair to him or unfair to me.
