I somehow managed to work how to make myself cum at 4 years old, the reason I know I was that young is that my family moved house before I turned 5, and it happened at the old house. Managed to repeat it every night for pretty much the next 20 years. Had a few weekends off when I went to scout camps and we had dorms to sleep in, then school trip for a week aged 12, then longest was 2 weeks when aged 21 on a lads holiday to ibiza after graduation. Now go through phases of twice a day down to once every 3 days. No way I could ever last 6 weeks, never mind 6 months.
