no means no, but what if they say nothing? or like, giggle or something like that? does that mean no too
saying nothing is not generally consent
some states, such as new york, are "yes means yes," which requires a
clear, positive affirmation before any sort of loveual activity. other states, such as florida, are more ambiguous, as consent can be established through things like body language or prior relationships instead.
however, i don't think "giggling" would automatically be considered consent, as many people laugh when they're nervous.
