Maybe going totally no fap. No Fap can sometimes work wonders for all of these types of things. It aint easy. The longest I did no fap was 2 months but felt like superman. I went totally No PMO. No Porn, no Masturbation and no Orgasm. When it ended, it was an explosion like a when you were a freshman in high school.
Go on youtube and search "The benefits of no fap".
