so itchy.

So I usually masterbate by rubbing my clit and working down to my vagina. Afterwards it usually burns when I pee but I've heard that that's normal. However two nights ago I think I went too hard? Now my vagina is irritated I think. Is this normal? it gets really itchy but it's not red or infected that I can tell. I'm looking for a way to soothe the itchiness.
