awkward question for PTs

i (56 m) have been going to a pelvic floor PT for a few months now. we are making good progress, learning lots, and am pleased with results. for all these visits so far i’ve done prep, laxative night before and enema day of. is this necessary and helpful for internal work? it’s not always easy to tell if someone is home and this routine can be a bit much sometimes. PTs probably deal with this stuff every day and sure, i could ask, but don’t to be weird. appreciate any advice.
