Hello, I'm here with some facts! Some people have very sensitive nipples and some barely feel anything; it has nothing to do with gender. The most that can come from nipple stimulation is probably just a ticklish feeling or arousal that makes males/females horny but it'll never be so intense as to make them moan :/ some men even get turned on by their undershirt touching their nipples so yaoi is just an exaggeration based on truths
I always see in smut and yaoi how a person screams when someone licks their nipples. Is this common? In no way I ever felt like screaming or moaning loudly from this. Sometimes I envy fiction.
