Relationship where one person loves sex and the other doesn’t ?

I totally hate sex. I really can’t explain why. Please don’t get me wrong, my husband is the best! Absolutely Best but I just don’t like sex or enjoy the act of it. I always pretend to enjoy it when with my husband but he knows I don’t. I always make excuses when he starts initiating sex. I know this isn’t good. My husband loves sex so much... how can I balance this? Is there anything I can be taking to improve my sex drive!l? I want to please my man

I have been through the route of therapist. She thinks it’s because I lost my virginity at the age of 16 through rape and I was raped by my uncle too. how do I overcome this hate for sex? No one is really helping me in that aspect. I feel for my husband and him having to endure having sex like once every three months
