sharp pains?

(this problem is nsfw, talks about masturbating) hey gals, I know this is odd but I don't know what's going on. so earlier today, about 4 hours ago, I masturbated clitorally. it was just like any other time, no pain (during or after) or anything and I had an orgasm. now, about 4 hours later, when I touch my clit I feel a sharp pain. this has never happened to me before and I don't know what's going on, but hopefully I can get some help through here. please comment advice or if you know what's happening and how to stop it. thanks ladies!

(P.S. I am a virgin, I've never engaged in sexual activity so sex can't be the cause.)
