Are these dudes really 'straight as an arrow'?

There are three guys from my town aged from 35 to 65 that work and like to spend a lot of time together.

The thing is that not only do they define themselves as 'straight as an arrow' but they're are also somewhat homophobic (they crack jokes about gays all the time) and like to act macho.

What surprises me is that this clique of "macho men" do the following:

-They work together for more than 6 hours per day, and stay together when it's time to take a break.

-In spite of the COVID-19 pandemic, they drink beer, smoke and stay close to one another while they chat (with no masks).

-They touch each other (which includes hugging and patting on the back and shoulders).

-They talk about everything, including private thoughts and feelings that not even their female partners are aware of.

-They also meet when it's a holiday, leaving their wives alone. This means they prefer to hang out with their male friends than with their female partner.

Are these guys really straight or their attitude is just a facade?
