We used to call women who preferred the company of gay men as
What are straight men who prefer the company of gay men called? I found nothing on the internet, unless you count Urban.
Based on the comparison to the term "fag hag", I assume you want a term that could be used in similar contexts, regardless of whether some people might find the term tasteless or unpleasant (some women find the term "fag hag" offensive, and I assume the terms I list below could also cause offense).
I think "fag hag" is more frequent than any term that specifically refers to a man. So I think the most obvious way to express the idea would just be "male fag hag", which has a number of hits on Google.
When I searched for that phrase, I also found the following terms...
Using Google, I found a couple sources that give the term "fruit fly". It seems to be a similar term that doesn't have to refer to a man, but that could be used to refer to a man.

See, this is why I like the term "fruit fly." I refer to my female hang out buds as fruit flies. Don't know if Lesbians mind being referred to as fruits or not, but the term could work for anybody, I guess. Heh. I've got straight male buds who I've told hangin' round with me makes them fruit flies.

The thread is about a term for men who prefer the company of lesbians, but the context implies that swampbear is a gay man who uses the term "fruit fly" to refer to people, male or female, who like to hang out with gay men (or women).
I am a Fruit Fly, for sure! Honestly, except for 2 of them, every man I've been friends with or romatically interested in have been gay! It became quite depressing until my boyfriend came along. [...] I guess I'm a gay man trapped in a woman's body.

There are also some people who replace either "fag" or "hag" with "stag" in order to imply a specifically male equivalent.
Canonically 'fag stag' is the term for a straight guy who hangs out with mostly gay dudes.
