There is nothing that protects the vaginal opening before a period. The vaginal opening is always covered by labia majora and minora (inner and outer "lips") along with the pubic hairs (which is prevent dust and other irritants to enter the skin folds.
There is a film of skin called the Hymen that partially covers the vagina which breaks away during puberty or through early sexual behaviours such as masturbation.
Vaginal discharge starts as you enter puberty, there is no way of telling when your period will start by when you started to get discharge. The most that can be said is that menstruation normally starts within four years of starting puberty.
Because it's natural for the opening to be small before having sex. Once you have sex it will naturally get bigger and bigger!
to be honest the warmest part of a human body before death is in the anus and vaginal opening/ urethra.
The vagina is like before pregnancy but the cervix, the opening to the uterus, is closed by a mucus plug.
A girl's first vaginal discharge usually occurs anywhere from 6 to 18 months before their first period, or menarche. It's a sign that puberty is in full swing.
Before Puberty begins you are growing at a slightly slower rate.
Before Puberty, girls grow as children. They do not develop sexually until Puberty and hormones start.
I think you're referring to an "episiotomy", which is the surgical cut made right before delivery, between the vaginal opening and the anus (helps keep the area from tearing during delivery).
You have a growth spurt before puberty when you are age 7-9. And you will have your next growth spurt during puberty, usually age 13-15.
Before puberty the penis doesn't grow very much at all, and there isn't anything you can do to change that. Your penis will begin to grow when you begin puberty.
