I'm sure doctors have seen worse or funnier things. If you want to have children later in life, you may want to seek medical attention and make sure you haven't damaged anything permanently. good luck.
If your that emberrassed go to a hospital that is outside your normal territory. Just out of curiousity are you male or female?
I think you'd be supprised what they have seen at the doctors. I knew a nurse that had all kinds of stories about women (and men) coming in with things stuck inside their body, to having rashes from using weird stuff to masturbate. One guy used a cantalope after he put a hole in it, and put it in the microwave to warm it up. Well, he made it too hot and got 2nd degree burns on his penis...
go to the ER! Please, don't be ashamed, you need medical attention, you could have seriously hurt yourself. In a few years, you will just look back on this and laugh, and be happy that you went to the ER before this got worse!
