Quite an interesting talk. The notion that the brain is always after “new mates” ran true to me. My pornographic tastes are always fluctuating, and I always find myself search out new porn. The weight of anecdotal evidence that’s now appearing with men speaking out against compulsive and addictive behavior towards porn is overwhelming. There’s even a group of people on The Student Room with the aim not to masturbate for the whole of 2013. I am seriously considering quitting for good.
