I have my most massive erections and cumshots when I have abstained for 7 days. Not 5, not 6, not 8 or even 11 days. It's 7 days. There are Chinese clinical studies that tested men's testosterone in lab settings and there is a significant spike on Day 7 only, not before and not after. I had 2 years of travel back and forth for school and had lots of different stints of different numbers of days I did not cum (or even really masturbate just to play with my erection). Any day after 4 days was fucking great and amazing. But that 7th day, they are always ones to write home about, swear to god! And I've repeated this 7-day thing multiple times even when not traveling but just at home, and every time, it's my biggest, furthest shot. I'm not the biggest most consistent shooter, but whereas I might normally have one big shot on the first rope and then decent ropes that don't shoot as far (I'm talking one hits my wife's neck or hair, the next 2 or 3 hit her breasts and stomach), on Day 7 I'm shooting past her head and then on her face/hair, and then breasts!
