I believe about 1/2 an hour is what I have read.
Women can not 'squirt semen' because they simply do not have the parts that make semen. But they can 'ejaculate' some sort of substance from the vagina.
Your question is not entirely coherent. Although, I think you're asking how long semen can be detected in the vagina for an analysis. Semen can live up to 5 days in the vagina and still be analyzed.
The semen is expelled from the penis, into the female vagina.
It really doesn't matter as long as the semen is introduced into the vagina.
Semen has to be inside the vagina for you to get pregnant.
By having sex and sticking your erect penis into a woman's vagina and ejaculating, releasing semen into her vagina.
They fit their whole hand into your vagina and dig around to find the semen in your vagina.
Not unless curling irons have started to ejaculate semen. And curling irons is not something you should put inside the vagina.
The semen is released into the vagina, while the egg is reaching the lining of the uterus, the sperm penetrates the egg.
What is leaking from the vagina is not the 'cum' all together. the semen, or the liquid that protects the sperm from the women's natural defences, have no reason to remain in the vagina once the sperm have collected into a place called 'the sperm pool' which holds the sperm until the cervix or the small opening that leads to the uterus opens and allowd the sperm to move in and find the egg. Thus the semen is leaked back out of the vagina, since it is not needed in the body anymore.
Semen is the clear while sperm is the white. The semen protects the sperm as it enters the vagina
The size of the syringe doesn't really matter. A turkey baster will work just fine, though an eye dropper should work. The main thing is getting the semen into the vagina. How it gets in there doesn't really matter as long as the sperm cells in the semen are fresh and viable.
