Am I weird and how do I ??

So my hubby of 4 yrs now doesn't know something about me I'm kinda scared to tell him cuz I would know his reaction... Or I don't know how to tell him ... But I get turned on by gays , lez , and animals mating ... I don't know why but I just do and nobody in the world knows this ... It has turned me on since I was 7 ... What do I do ???
