"What she really means when she says 'no' to sex"
" acting abruptly on your impulses can put her under pressure and be real turn-off. Giving her time to warm up to the idea can change the whole course of your evening."
" But feeling suddenly groped isn’t always exciting for women."
IMO these are great suggestions and are in no way suggesting that a man should ignore what his partners say.
The article is saying that you got a no because of these reasons. Next time, try this and you are more likely to get a yes.
The title of the piece is What she really means when she says 'no' to sex. So the bit about why he says no is extra.
It's hardly claiming to be a comprehensive explaination of why your partner says no, exploring the variables, techniques and emotions.
