First time Masturbating gone wrong??

Hi girlies! I need some help here, I don’t really know if I wanna masturbate anymore because I feel like I’m gonna hurt myself more. I’m sorry if it’s really tmi but I was fingering myself in my vajj and it feels like my flaps are burning! Am I just sensitive or is it normal to feel this way??? I’m 17 and a virgin (who’s period is very irregular)

Please help! Thank you💞
