Assuming a person born in 2000, with a 100 year life expectancy for easy math. In order to live to 3263, would need to live 1263 years, or 1263% life expectancy, which would mean 100% by default + 1163% via masturbation. So masturbate an average of 58,15 times per week, or 8,3 times per day.

It would hurt a lot, but I can see it being possible.
