I THOUGHT HE WAS PEEING I WAS SO UNCOMFORTABLE IN THAT SCENE
Lol its not pee. Actually all women squirt while having an orgasm its just that for some it doesnt go outside, it goes back to the bladder. It's a transparent fluid containing fructose so... its sweet. Thats also why women often go to pee after sex/or even masturbation. I dont really know if men can squirt in reality. It should be possible? He probably feels humiliated (to squirt like a girl) or too simulated so thats why he doesnt want it.
Okay correct me if I'm wrong but I thought squirting was like the *best* way to cum? But Soohwa seems uncomfortable with it. Is it uncomfortable or something? Also I don't think I've ever read a yaoi where anyone squirted so it's pretty interesting tbh.
