Well I am not a man so I can't say if they would be decensitized by seeing breasts on a regular basis in a (non) sexual context.
I do know that many porn addicts have to find more extreme pornograghy because they do become decenitized to the run of the mill porn offerings.
What I can say is that I appreciate you taking the time to critique my response, and I agree that although we disagree, it's always great to read other viewpoints that challenge your own thinking. Cheers!!
