A blow to the vulva is as painful as a blow to the testicles, women can feel that pain just like a man can, get it through your head that women have a weak spot too, sure the testicles are larger in volume & therefore can be squeezed easier, but a hard kick to the vulva is as painful as a hard kick to the testicles.
By the way, a broken bone is a billion times more painful than being hit in the testicles, I broke my arm when I was 8, & my father forced me to eat a pie, then have a bath, & then go to bed cause he claimed it was a 'bruised bone' & he said no son of his would see a doctor, & my mum took me to the doctor the next day & the GP confirmed it was broken, & the pain I felt from that fractured radius was the most excruciating pain I ever felt, it was a billion times more painful than the time I was hit in the testicles really really really hard.
It was so painful that trying to rotate my arm just a millimetre caused so much pain I almost passed out, I have been hit really hard in the testicles but could still move, & when hit in the testicles the majority of the sensation felt is nausea & pain in the lower abdomen.[/i]
