Yes, that is called vaginismus. As long as it doesnt take a long time to contract.
No, mucus in the vagina is normal and is sometimes a sign of increased fertility
its a normal to have a pimple in my vagina?
Not normal.
No the vagina goes back to normal after.
yes that is perfectly normal, if by Virginia you mean vagina
Not usually. Sometimes, there can be damage (for example from sexual abuse) from tissue tearing and a hole called a fistula can open up between the bum and vagina. This is a serious medical problem and should be refered to a hospital.
normal
It could result in an infection, so is not normal.
Yes it can. The Vagina is cleaning itself out and old blood gets brown and sometimes even clumpy. It is perfectly normal and you don't need to worry.
When a female is not fully aroused her vagina is in it's normal location (shallow) as she gets more "in the mood" the vagina stretches out and the uterus moves higher in the body allowing deeper penetration (not shallow) the body does this so that there is a higher chance of conception, (sex is supposed to make babies)
The normal pH of semen is 7.2-8.0 so somewhat alkaline.
I'm not a medical professional, but I believe it's normal. It can happen during activities such as yoga or sex, and it is sometimes referred to as a queef.
