ok so basically its like this. you see the corpus cavernosum? you can think of that as like. a big sponge that fills up with blood. so when you get an erection thats actually just the same as a hydraulic effect like its water pressure making it turgid. like a balloon with just a little water is soft and squishy right? but if it has a BUNCH of water in it its hard and you can't really squish it anymore! the actual mechanism by which an erection is produced is super complex cause its like the wholeee nervous system its crazy i want to read into it more cause its really cool. one thing i particularly like is that there isn't a gland or something that controls blood flow to the penis its produced by dilating the arteries that supply it manually by supplying nitric oxide to the smooth muscle in their walls. another thing that rules is that some people can actually become erect just by thinking about it... isn't the human brain incredible... i wonder what step in that process causes a reduction in erection strength from hrt? do the smooth muscles weaken? im curious... i wanna research it
