I do it to relax, and to hopefully have a better night sleep. For a handful of years, I'll think and realize I haven't jerked off yet, and then think, "Well, maybe I'll just get it out of the way now" or delaying it, hoping an urge comes over me, allowing me then to go to my favorite accompanying site. For 20 years, it's been a pain to piss out the excess semen. Sometimes it hurts so bad, I go take a shower. A problem of mine is that I don't eat anything until night, and so there's nothing to absorb the soda I drink during the day.
A chore? Gosh no! I love to masturbate. Have been doing it for over 50, maybe nearer 60 years. I'll masturbate to orgasm 5 to 7 times a week. Then a bunch of times where I just get myself erect and enjoy some good feelings before stopping for a while. There's no chore to it when it feels so good.
