Perineal Massage: Worth it or skip it?

My pelvic floor PT suggested doing perineal massage every other day starting 36weeks. I trust her, I really do, but I can’t bring myself to do it on my own. And it feels weird to have my husband does it idk why!!! Like I’m afraid it will hurt?! My PT did say it would be a little uncomfortable, but not painful. What do we think? Are you guys doing it? Is it actually helping with tearing? Am I overthinking this and should just do it???
