It is normal to look at pron, as long as we dont do it...
How can't it be embarrassing? Are you saying that if that person would not mind you wouldn't mind either being there while he was doing it?I mean, in a very un-probable case both people wouldn't mind (like in most sex fantasy's), but in the most probable cases it would be 1 guys catching another one doing it, or a parent catching their child maybe you?(suposing you are young...) doing it.
