There was a previous question as to whether or not masturbation is a mortal sin or not.
Fr. Vincent Serpa bluntly answered yes it is a mortal sin and one must go to confession. I know masturbation is a sin of grave matter and meets the seriousness of sin required for sin to be mortal. What about habitual masturbation/pornography which usually go hand in hand and where “Full consent” comes in? How can one discern whether or not he is in mortal sin when a sin becomes habitual? Priests often have varying answers that confuse laity.
