Men want to know their partner isn't fantasizing about some other man during sex, so they like the partner to verbalize (talk about it). Porn dialog apparently will turn their motor just fine. In a survey men picked these phrases as their favorites to hear during sex:
“Oh, yeah, right there!”
“That feels amazing”
“Don’t stop, harder”
“I want you so bad”
“Give it to me!”
“You animal!”
“That feels amazing”
“Don’t stop, harder”
“I want you so bad”
“Give it to me!”
“You animal!”
