Yes Ive done them few times over the years
Like most of us women we would never win a physical fight with a man (as a rule ) but knowing how to punch properly and for a women the palm of your hand flat out to hit in the face ( so Palm facing the face ) is far far more effective than trying to punch a bloke if you don't know how to make a fist properly you will end up breaking your thumb in the process ( yes I've broken my thumb
)
But hitting direct with your palm is enough to break a nose with not much pressure or power
Like wise trying to use a weapon like a base ball bat isn't advisable as its more likely to be used on you instead
Biting the nose is probably the best place to bite someone it's seriously painful rather Than going for the balls
Classes that teach you how to get out of arm locks/being restrained by using your own body weight is what I would be looking for
