While not a testicle example, ThisTroper, who is a speedrunner, actually cringes in pain whenever he sees an obvious big mistake in a 'run. So in a way he shares his pain.

This troper is female and cringes at groin kicks.

Same.

MeToo

It's strange how we do that too, isn't it? I mean, we don't even have them, but a hard enough shot makes us cringe almost as bad as the boys.

My fellow females and other tropers, I have a theory. See, the external part of our clitoris has the same amount of nerves as a penis, but it's (usually) quite, quite small and protected by our labia. However, if someone's aim was just right, an otherwise mildly inconvenient GroinAttack on a woman would make her take it like a man quite literally, sprinkled with an extra dose of WTF.

This female troper, when she was about 10-12 years old, borrowed her brother's bicycle to go down the street. Upon reaching her destination, she leapt off the bike just as she did on her own, forgetting that the crossbar is much higher on men's bikes. She can verify that the above troper's theory is correct.

I do the same thing. You don't have to have it to feel empathy for someone in pain.

This troper was playing ''BatmanArkhamAsylum'' when his brother came into the room. Just as he came in, Batman was doing a slow motion take-down that consisted of lifting the guy's leg and kneeing him square in the balls. Said brother just cringed.

This troper reacted similarly to the castration scene at the end of {{Hostel}}2.

On Thanksgiving, this troper's teacher showed us a video that detailed the processing and serving of turkeys, among other things. At one point, we were treated to several shots of a chef diligently cutting up turkey testicles, prompting the guys in the class to begin wincing and groaning loudly.

A Share The Female Pain example: My reaction to the opening of {{Eiken}}. FYI: ''bouncing like that would hurt like '''FUCK.''' ''

This male troper suddenly has a feeling of unexplained sympathy for endowed females.

Holy.... That was just traumatic. Excuse me while I go bind my chest now.

Ow! Geez! {holds chest down} Just...oww...

Uhm...this male troper doesn't get it. Sounds gross, but can any of you girls can describe me how that feels?

I'm a guy as well, but an approximation is to tape small bags of sand to your chest, right over your nipples. Make sure the bags weigh a pound or two. Also, make sure they're as tight as possible. Okay, not grab them and start pulling them in different directions. It hurts like the dickens, even more so peeling the tape off afterward.

Oooooh, I see. Sounds like level 5 on the pain chart.

HOLY MACKEREL OW, OW, OW OW OW. -clutches chest- Breasts are not supposed to do that!

This male Troper would like to say this looks very very very... screw that, words can not describe how painful that would feel.

This editor saw a scan from Cattleya's game book, at which point he cringed as his nonexistent breasts wept in sympathy.

One ''female'' troper has this sympathy pain for both sexes, and even reacts with winces and cringes to pictures of nipple or genital piercing. She has too vivid an imagination and can imagine the probable pain level of the actual impact/piercing/etc.

This (female) troper likes to invoke this trope by casually mentioning the word "castration" to a group of males and laughing as they all cringe (considering how much she hates her uterus, attempts to make her cringe at the word "hysterectomy" tend to not work). She'd also like to correctly refer to it as an "orichidectomy", but is afraid no one else would get it.

I hope you only do it to guys that are Jerkassess, springing something like that on an unsuspecting group of average guys is just cruel. :(

In one forum, we were discussing clitoridectomy, and a girl just wrote "[=*crosses legs*=]".

This troper was taking an anthropology class. We were talking about initiation rites. When we got to circumcision in Africa, every male's hands were over his groin.

Gender-flipped in this troper's sociology class. We were watching a video about female genital mutilation in Africa and...yeah..

After reading this Cracked article, this (male) troper couldnt avoid feeling the pain. The hillarious part is that even his sister and (female) friend could feel it, particullary when reading #1 on the list.

This link, Batman copping it this time...ouch doesn't even begin to describe it. For those wanting to know here's the link. WARNING: The person who ripped this must think this is FetishFuel considering the slow-motion replay. This troper just thought it was painful, especially since it ''is'' Batman getting thusly pained, to the degree of feeling as if groin of my soul was being abused like that as well...

Inverted for this female trooper. I was at my dorm floor when her floor mates shrieked and cringed at a story where a girl shaved her ''nipple'' off. All of us responded with protectively hugging our chests.

Same here. This troper and a bunch of classmates were looking at a news story about a snake who bit a model's breast. We watched the actual video, and when the snake started biting, every girl who was watching clutched their boob and groaned/cringed in sympathy.

This Troper, at the ripe old age of 16, acquired a rather 'unusual' genital piercing. Said piercing is called the 'Apadravya', and he will caution you before you go google for pictures of what it is. The procedure is to pierce a 1.12mm diameter (at smallest) hollow needle through the glans (head) of a fully erect penis. Because I have a high pain tolerance, the actual piercing stage didn't hurt all that badly; however, the clamp that is required to flatten and 'thin out' the area is quite discomforting and was the worst part for me. But yeah guys, imagine a needle going straight through your raging manhood.

TheOtherWiki actually has a picture of this accompanying an explanatory article. I'm female, and I'm crossing my legs in response.

Literal example: in 9th grade, this male troper was harassed by a fat, fugly female bully. One day, said bully approached this troper and tried to convince him that all the harassment was just good fun. She never finished whatever she meant to say because this troper hit her with a knee to the cooch, learning in the while that females are vulnerable down there too.
