My results with Semen Retention

Okay, so I am relatively new to nofap in general. I've been addicted to porn for about 5 years give or take, and I have developed some good habits and a healthy lifestyle to stop fairly well. Every few weeks I may watch some porn, but aside from the casual mistake from take to time I am making very good progress thus far. My big question comes from my experience with semen retention. I am currently 6'0 220lbs and actively participating in boxing and MMA. In previous years while playing football I would bust about 2 or 3 solid nuts per day, and I always felt sluggish. However whenever I stop porn and busting nuts all together I have surges of physical strength and energy, and my workouts are far more intense and my academic success is more noticeable. But the big bummer for me is that around day 4-5 of abstaining from porn/masturbation, I begin to feel all the SEXUAL energy wear off. My physical energy is there (MMA etc) but I dont get hard as often, or at all without actually trying myself. My sexual drive is lowered with each day past day 4-5ish. I found it is best to cycle the abstinence, such as 5 days on and then bust (without porn), repeat. Any thoughts or similar experiences? I would appreciate some open discussion on this topic.
