Hurt is rug burns, injured is going to the ER and walking out after imaging scans wearing a neck brace.
You don't laugh at women over shit like this, it causes them very real pain. This has nothing to do with political correctness, this is about trying to understand the feminine psyche, accepting there is a difference in the way men and women operate and having compassion for a woman's heart and mind. Other dudes, yes, fine, joke around with them, they don't give a shit. The woman you sleep with though? Totally different story. Finding humor in a situation like this when she's not ready only causes her to get hurt, because now not only does her body ache, her heart does, as well. She feels like you're making a joke out of her feelings, both physical and emotional. That you're trivializing what she feels.
And for the love of all that's holy at least give me the credit of trying to explain one facet of a woman's mind to you guys instead of telling me I don't know what I'm talking about. I am a girl, you know, I think I understand women pretty well.
