Do I have ? I am a virgin but still not sure?

okay so i am 14 years old, I'm a virgin. So recently I have been master bating off the hook and I am disappointed in myself very much. Recently like 5 days ago I stopped master bating and now my hurts. Is this just because I am not used to not doing it? because before I stopped it did not hurt at all. also a while ago I used my Silvia as lube and got a small blister but that turned into a purple little thing which I believe was just a small blood blister. Please tell me I am okay!!!! THANK YOU SO MUCH!!!!!
