Like, what causes it to get hard? I hear its because of a rush of blood to the area but I dont think I get how that would keep it rock hard

It's not like it's hollow and fills with blood, it's more like a sponge

But yes it's just blood pressure that makes it hard

oh that makes more sense, but still its not like a sponge can get rock hard after being doused in liquid right?

If you put the sponge inside a condom and forced the water into it, it would get hard

ah ok

I find it pretty cool our bodies know to regulate blood flow to the area anytime we get horny

It's not so complex, when you get turned on it stimulates a nerve that relaxes the muscle "gates" to the sponge, and blood flows in

And traps the blood inside the penis to maintain rigidness. However if you're bitten by a Brazilian Wandering Spider then the "gate" can't open so your penis gets filled with blood but it can't return to the body. Unless you seek medical attention fast you risk losing your friend (this is also the same reason why you need to seek medical attention incase Viagra gives you over 4 hours erection).
