Unpopular opinion ahead - I don't believe in this "NO means NO" thing in relationships (note - this isn't including rape of any kind.. I'm talking committed sexual relationships.. lovers.. spouses etc..)
'No' in these relationships often turn to 'Yes' with very little prompting.. why not sex?
"wanna go out tonight?
"no"
"but *insert reason*"
"oh - ok. Yes"
"Wanna pizza for dinner?"
"No"
"but *insert enticing ingredient*
"oh, ok then"
some changing of the mind takes a little more persuasion.. like visiting the mother in law
but bottom line, we all know persuasion works.
anyway.. "NO" is not always definite, and for some reason many think "I'm tired", "you're drunk", "not now" .. even mere silence means NO too. It doesn't.
I would think that communication within a relationship is such that when one says NO (for real) that it really means "NO".. not just "no" sometimes.. and clearly those who are complaining about 'not being understood' or expecting their partners to read minds should look into bettering their relationship communication thus making this topic moot.
