Only if the girl is literally trying to kill me.

If you think that you, as a girl / woman, can freely hit a man without fearing the consequences, because you are labeled as the weaker gender, then you deserve to be hit back. So yes, punch away.

Hit me, I hit back. Doesn't matter who it is. Get your hands off my person.

Actually, I'd say that it depends. If she hits me once, and then is making the motion to hit me again, I'd probably try to pre-empt her.

I would, and have many times. With my penis.

In a relationship /marriage, no i won't punch my wife.' If it's something so SEVERE, then it wouldn't be more than a slap, like the good old fashion ways seen in movies.one that doesn't inflict bruising or bleeding that's for sure. What if some ugly big girl came at me with a weapon, i would think i would try to tackle or keep my distance, but i wouldn't want to punch or kick anyone.

I never really understood why it’s more taboo to hit a girl than a guy. Like most here - if I was really threatened I would hit back, regardless lol. I don’t have some misconception that women are fragile and weak

Only in the interest of self-defense.

Like I do with everyone else, though I probably wouldn't punch an attack helicopter.

Yes if I have to defend myself
Same goes for a guy.

I hope you're joking. If not you're a shitty person.
