My last job was in a small team like this and I didn't quite 'come out' per se but added everyone on Facebook, which made it fairly clear as I'd had pictures of myself on holiday with my boyfriend or whatever. I didn't get any awkwardness from it, and most of the lads made a point of including me and asking questions about The Culture and what I'd been up to at the weekend. You'd be surprised at how open a lot of guys are nowadays about wanting to know about it all. The fact it's a small team means that everyone's a bit on the same page: if something gets too offensive, it affects the entire team, and they all understood that. If you've not watched clips of Courtney Act/Shane J on this year's CBB it's a perfect way of balancing the act of being one of 'us' and integrating yourself with groups of laddy straight men. Part of it is about being assertive, confident and willing to educate in a non-preachy way, but also understanding that this 'banter' is how a certain generation of buttoned-up straight men communicate and let off steam. You're not doing yourself a disservice if you take part every once in a while as long as everyone understands your position on it. If it crosses a line into something more toxic, then make it known.
