Im bottom but sometimes i want to top

I'm 100% bottom. But sometimes I feel a desire to be top. But this desire goes away after I ejaculate. I don't accept this side of me!!! In fact, I hate it! . I want to stop feeling this way... My therapist said I should accept it, but I can't. It's not part of me, it's not me. It's like a bad addiction. I wanted to find someone with the same problem.
