I MUST put your mind at ease, given the nature of recent discussions. You ARE NOT borderline abusive.
Let me give you an absolute CLEAR indiacaion of abuse. When a woman tells you to stop, no, that hurts, please, no, stop... and you don't... you are headed into dangerous terrirtory. If tears of FRIGHT are involved, you are headed into dangerous territory. If a woman FIGHTS you, and you ignore her... you are headed into dangerous territory.
There is nothing WRONG with being a bit aggressive, especially if she asks it of you. If you check in with her, ask her if its okay... etc., etc... and you are proceeding with approval... fine... but don't go so far as to HURT someone.
A body is designed to respond in a certain ways, regardless of what the mind wishes. In states of extreme fright, a body can respond in ways that mimic excitment just to protect itself.
You are a sensitive man. You are AWARE of your wife, and more importantly, of your actions. Your actual RELUCTANCE into such waters indicates your sensitivity. Do not allow arousal to overcome it. You will know. You will know.
You are not an abuser, GGB. Sometimes sex CAN get a bit bawdy. Fine. If it is happening to a point that makes YOU uncomfortable, stop it.
You have control. Sex can't happen without YOU, kwis?
