I am more comfortable fighting someone bigger than me tbh. I'm pretty smol both weight and height-wise. I have bare knuckle boxed way bigger and frankly way tougher friends, like old school train hoppers, pre oogle era, and also more recently did some free form grappling with a co-worker who was just short of representing Japan in the Olympics for judo. Turns out a lot of judo stuff comes natural to me cause I used to fight people bigger than me a lot, and also I can strafe around a large person faster than they can turn on the spot and most of my body is below their shoulders so all I reslly need to worry about is my head cause body shots would be awkward. Real fighting is another whole thing and i'm hust not doing that as an adult, too dangerous.
