Men are sexually stimulated almost wholly by visuals. Some women enjoy porn, but any attack on porn is a direct attack on men. Also, many men will spontaneously ejaculate if not stimulated. Honestly, it is not much different than needing to urinate or defecate. It is a bodily function that must be taken care of or your body will take care of it for you. Watching porn is not a bad thing. Some porn is bad, but watching it certainly is not.
