I get turned on by pictures of women, but I’m straight?

Is this a normal thing? Pictures of sexy women get me hot, but in real life my partner is a man and sex with a woman doesn’t sound all that appealing. I like dicks and strong muscular arms. But looking at pictures of that doesn’t really turn me on so much. It doesn’t make sense.

Ps. I have tried exploring with women But I found it very uncomfortable and repelling irl. I am never attracted to women irl. And I wasn’t turned on by them naked irl either .
