yesterday i had sex after not being sexual active for a while, and almost immediately after wards a medium sized bulge exposed out of my vagina, it is very painful to walk and sit, i attempted to push it back inside me, but right after i moved my hands it slipped back out, i don't know what this is, whats going on, and or how to get rid of it. I cannot go to a doctor because my parents cannot know that i have been sexual active. PLEASE, if you have any idea of what this may be and how to be rid of it, i would appreciate your help. .
