Hi. I Am 15 And A Virgin, The Other Day

Hi. I am 15 and a virgin, the other day I was masturbating in the shower, and after that I think I got a large amount of water in my vagina. It doesn'5 run out of my body, beacuse I am a virgin and everything is sort of... closed off. And I have tried to stick my finger up there and get it out probably at least 50 times today but it wont get out. It feels like theres just this thing in there pushing to get out, and it is quite uncomfortable. It's keeping me from sleeping on schoolnights and I really just don'4 know what to do. Please help.
