I caught my husband doing the same thing. He was shaking the bed and i looked over at him and he's watching a video on his phone just going at it, vigorously masturbating. I got really pissed because he KNOWS I love sex and he didnt bother waking me up. He gave me some bullshit story of wanting to be respectful and not wake me up to get him off. I think what pissed me off the most isnt the fact of him masturbating. Its the fact that he prefers the porn stars to his own wife. Needless to say we got into a heated argument about it. He told me to just drop it and I asked him this: if it were me and the roles were reversed, you'd be pissed off too, wouldn't you? See it from the woman's point of view. So.. That's my advice or all the men out there that do this shit. See it from our point of view. Put yourself in our shoes and think of what we go through when you do this.
