Babysteps
selfish?! That deserves to go in the "Laughter is the Best Medicine" group (which was founded by whom???).
But yes, you Babysteps, most unselfish of men, would feel selfish for easing up on your "output" here. That's who you are.
Personally, I would much rather get a rare, occasional Babysteps fix than have you burnout and collapse.
Everyone here has the right to determine their own level and type of participation, and personal needs legitimately top the underlying considerations for those decisions.

Babysteps!
