One of the things that probably annoys me more than the average person is when people respond to porn with silly little comments designed to undermine the hotness of something and turn it into a joke.
Like yes, I get it, you are ashamed of sex and think it is somehow more acceptable if you show your mates you find it funny. But actually... I'm not ashamed of what I do, and the people who wank to it probably aren't ashamed either, you just look like a tedious nob.
