I haven't had many fights for real, I used to fight for fun but not serious as i'm a pretty anti-violant person, however I had got alot of those "provement thing in my past from guys to show I was one of them. climp this planket, show your strenght, do this do that and if not then im a sissy. I guess I also acted more thought for this but now I notice this isnt worth it.
I see many guys going around proving themself and there strenght, hearing comment like "real men do" or "I know what woman want" but when you get more into it there really pitiful people who desperatly want to hang on to something.
some year ago there where a 2 guys from my school, Both where pretty rough and strong, tall, musculour and general masuline on the outside but not on the inside. One of the guys used to be kinda dominant in everything he did, I was opposite of him and usunally got comment of "boys dont do this"
one time I walked in my neighbours room I saw him sitting there with a pink hallo kitty sticking plaster which his girlfriend had putted on him head. I ask why he do not go out and eat and he say he hurted himself so she where putting on sticky marks on the wound. I say its only just a scrats and he say "but the other boys will bully me when they see its hallo kitty!

"
(and btw he was over 20 at that time)
I still find it pretty ammusing thinking about how big and strong he always apears exept for when you get into details,
most guys are like that. The other guy he was in the closet and actually kinda femenine but tried hide it alittle the first time so nobody would comment on him or give him trouble.
He also apears very strong on the outside but inside he was very scared afraid of what other thought of him, afraid of him famely which he wouldnt lose yet never really could do him good and he was also abit scared when I showed him around in my neighbourhood just to creep him out abit

.
but yeah my suggeston is don't start a fight just to start a fight or prove yourself. Its a pitifull concept made by pitifull people with low self esteam. If you must hit on random people to make yourself feel better or proving yourself then your are on the same leve.
if guys desperatly want to fight either ask them dirrectly why they want to fight, what there goal is, why they think boys should fight, if there isnt more in the deffenition to a guy than fighting, stuff like that usenally confusses cisgenders who usunally dont really questionate there actions, in some caises it also makes them pretty angry so then its better to just leave them alone if posible.
