I’ve worked in a place that was all guys until we got our maybe eight team member. We got two more women shortly after that. This was more than a decade ago and we were always a pretty tight group but we didn’t have a chat platform we could use at the time. I don’t think there’s anything weird about doing what’s normal with and just trying to be pals.
Don’t take any shit like misogynistic humor. Shut it down the first time it happens to establish boundaries cause it’ll be harder to reign in when it’s a habit. Good luck!
