I remember when i was younger how drool was supposed to be super gross, and now people see it as a maddening state of arousal. It's funny how nature do that

Okay no, childhood drooling is just poor motor control from malformed reflexes,
adulthood drooling comes from either the above, or sexual arousal that impedes previously reliable motor control over the mouth region.

Even then, this is more common in anime than in real life

**** man im trying to be poetic here.

Nah man what you said gave me a disturbing image of some toddler drooling because she was horny. My dick shrank 3 sizes today because of that. As if it wasn't small enough as it is!
