There are also a multitude of reasons to hesitate that aren’t “I want to say no but am afraid of saying it”. Such as stunned silence because he or she couldn’t believe someone so awesome wanted to have sex with them. Or confusion because it was loud and they misheard the word ‘sex’ as ‘sax’ and was wondering where they could possibly get one of those at this hour.

Also, auditory processing disorder. Give them a god damn minute.
