Taking care of perineum How can one take care of the perineum

Does anyone have any knowledge about this part of the body being affected by excessive sitting in meditation. I have had medical help, removal of cysts, haemorrhoids and general stiffness over my course of meditative life. 

Is this a normal problem with meditators and if yes how can one take care of this?

About me:
I am male, late 20s(fairly young to be having problems in that region?), sit cross legged (no lotus or half lotus), use a simple block, have had a history of stomach ailments since 12 (appendicitis, liver repair, bad digestive system), currently simple wholesome diet with no meat, eggs, do not drink/smoke.
If this is the case:


you can use a stool / chair or stadium seat
you can use orthopaedic cushions to added comfort
if sitting is a problem you can use another poster like lying down (don't use a cosy or luxurious bed as you will soon fall asleep. A hard surface may be best using a Yoga mat perhaps laying beaded seat cushion on top even if this causes you to fall asleep.)


Also when meditating try to keep your attention a bit longer in this region looking at the arising and passing away of sensation equanimously. Don't think of any healing or removing discomfort. Just keep your attention on the sensations. If this is Karmic, reducing your mental reaction for sensation resulting from karma means you will not be adding fuel to the karma prolonging it's results. If you react with any thing, like disappointment if any issue pops up, being happy when something does not pop up, etc. You are adding fuel to prolonging the ailment.
