Ah, you know, absolutely nothing wrong with slapping backs with the lads and making fart jokes. This is part of masculinity in my eyes.
What I'm trying to say it's recognise yourself as a whole, so whilst making fart jokes and comparing willy sizes with the lads, recognise that it's ok at times when you feel sad and a bit inferior. I do too at times. It's part of regular life.
Also, it's good to recognise when it's acceptable to do what. Probably making fart jokes and competing really hard isn't a great stance around women as it is with the lads.
