Please help. I'm a teenage virgin and I though this is embarrassing I am really scared because I noticed that there is a marble like lump on the deep inside part of my vagina... It's about a middle finger's distance in on the left side, i can move it a little and it doesn't hurt. It seems about the size of a marble but i freaked out and stopped touching it cuz i was scared so it might be a little bigger. i looked on some websites but couldn't find anything but a cyst. PLEASE help.
