Hi,

I totally agree with Hamster B.
If I walked in on my husband doing that would it hurt my feelings? Yeah, but I wouldn't ever consider it cheating. It's natural (masturbation) and almost everybody does it on occasion.

And porn is everywhere you look with the internet. Have I watched it, yeah sure, but not everyday. I think it becomes a problem if you can not have sex without porn, are watching or thinking about it all the time, or feel it is better with a virtual woman rather than your girlfriend. Nothing in your post made me think you believe anything of the sort btw.
