Fingering yourself?

Natasha • Periods suck

So, i've never actually put my fingers inside of myself..People always say how it feels good, etc., but I procrastinate and im not sure how to really do it without hurting myself accidentally or anything? It grosses me out time to time, i dont even have a reason for that. I literally rub my clit and around through my underwear. Is this even normal? I NEED TIPS/SUGGESTIONS URGENT!😂😂
