I keep having vaginal contractions throughout the day. it feels involuntary and doesn't hurt. i have a constant need to squeeze. how do i make it stop?

Have pelvic exam: It is not uncommon condition among young females. As physician i would ask any other symptoms associated with vaginal contraction. If you are sexually active young lady, i prefer pelvic exam and possible pap smear on the way and culture cervical fluid to rule out bacterial infection that can give you vaginosis. Talk to ob/gyn and will find out for you.
