I know this tweet is aimed at both genders and yes, blue balls are not a thing, I just want to add:

from the wikipedia for erection ‘As an autonomic nervous system response, an erection may result from a variety of stimuli, including sexual stimulation and sexual arousal, and is therefore not entirely under conscious control’

just cause they’re hard, doesn’t mean they want it, if someone says no, they mean it, no matter what their dick is doing
