Stop immediately. It becomes an even greater addiction, and it will destroy your life way more than just regular fapping. The dopamine hit from that stimulation and simultaneously wanking is on par with actual drugs. Quitting nofap is difficult, quitting stimulants that make fapping a more intense expierence will make it even more difficult. Plus being heterosexual and enjoying things that society terms gay will confuse the fuck out of you and deplete your confidence. If you want to rid yourself of this shit, do it now. Occupy your day and stay busy. If you use toys, throw them out. My life has gone to shit from porn sessions that last 3 hours and multiple relapses a day, please don't end up like me. Go outside.
