i can't comment on a c-sect as i haven't had one. but, like PacRakMG, i had an episiotomy for a forceps birth.

i had no issue with healing - i don't even recall any stinging/pain after about the first two days. i was offered pain relief in hospital but had one lot of panadol & that was it. i didn't find it difficult to clean in the shower or painful when i did so. they had prepped me for a c-section so i'd had an epidural before the epi was done so i can't comment on the pain of the epi itself.

i'm pretty sure we'd resumed DTD within 8-12 weeks but can't remember now! it was a little uncomfy at first but nothing painful & i've had no pain or issue since.

ETA - i also want to add that for whatever reason, i seem to heal quickly in general. i don't know if that's a legitimate medical thing or not, just an observation about myself! no idea if how you heal in general has any impact at all!
