I have this weird bump on my vagina show up every now and than but in different places. It only happens after a masterbate for a while and will stay for about a week. It's on my actual vagina (not the inside) . It doesn't have any different coloring, same color as my skin, it's really hard and does not hurt. Sometimes If I squeeze it it will hurt enough to make me cry and sometimes when I squeeze it juice will come out of it. I am not sexually active for some months so idk what it could be.
