Sit offset-so you are sitting on one thigh then the other when that happens.
I tilt my seat nose waaaay down
have a gigantic soft seat
and it has a cut out
But sometimes I sit offset-so I'm literally sitting on my thigh instead of my perineum
Granted you have to slightly lower your seat post-and your "stroke" will be a bit lopsided
but it beats "damage" and pain to a delicate area.
Don't put weight on your perineum-asking from problems-
granted you are faster sitting that way... but...
