Fiancé has odd fetish?

I’m not sure how to handle this but my fiancé told me today that he likes to watch gay porn. He told me he’s 100% straight though? I told him he can tell me anything and I won’t treat him any different. He told me that he thinks he watches it because of rape and sexual assault that happened to him when he was a young child. He said that watching that brings back memories.

So my thoughts are, wouldn’t watching that bring back bad memories? If it where me, I would want to stay away from anything that reminds me of a traumatic experience.

I know everyone handles things differently but I’m not sure what to do as a fiancé, he says he’s not bi but I’m confused.

Please excuse my ignorance if it comes across that way, i also apologize if this is a little dark. I’m generally just confused
