Is my boyfriend gay?

Don't give me hate. I just want some opinions.

I've been wondering if my boyfriend was gay because he's been to the ER a few times. He has seizures and has been having some underlying health issues. He even had a 4 day stay at a hospital recently. He always requests male doctors and nurses. Every man I know said if they have a choice they prefer a female because no man wants to be vulnerable around a male like that. My boyfriend also supposedly had been SA'd his junior year of college by a male so shouldn't that make him not want a male doctor even more? The only thing I can think of is he likes men. I know I shouldn't be thinking about this when he's having so many health issues.

I just can't help but wonder if he's gay or at least bi.
