I quit because I realized I had no idea who was and wasn't being raped. This is emotionally unpalatable. Likewise I realized I only found the whole thing vile after I had stopped for about a month.

Before you resist the idea of quitting you should consider your biochemistry might be a factor as well in your resistance. Take a long hiatus, and least a month and consider your own emotions about porn and your positive female relationships afterwards.

My two cents.
