If the boy ejaculates after withdrawing it from the vagina the chances of getting pregnant are much lower, but they are not zero, since there are a few sperm in the pre-ejaculate (precum), and she can get pregnant from this. Also, depending on where the sperm lands when he ejaculates makes a difference. If he were to ejaculate onto her belly or back, some could drip into her vagina and, though not as likely, can still cause pregnancy.
It's surprisingly easy to get pregnant if you're young and the intercourse was unprotected. A full ejaculation is not necessary for pregnancy to occur.
No.
In order for a woman to become pregnant, there needs to sperm present. Even if sperm is on another body part, but some of the sperm comes in contact with the vagina, she can still become pregnant. If it is on her fingers and she touches her vagina, there is a risk of pregnancy, although much, much smaller than with penile penetration
This is something I cannot answer. If you are old enough to produce sperm, then you have enough to get a girl pregnant. A male is capable of releasing small amounts to over a billion sperm when he ejaculates (http://www.livescience.com/mysteries/080606-llm-sperm.html). So, even if you don't ejaculate, but there is semen that comes in contact with your partner, she can become pregnant.
You can get pregnant when you have your period after, before and even long after you've had sex ... sperm can lay dormant for a long time inside of a women all it needs is warmth ...
There can be sperm present in the preseminal fluid, so there is a chance sperm could be in the vagina, and eventually enter the uterus, even if the man does not ejaculate until after he withdraws his penis from the vagina.
Yes. Most women get pregnant that way. The guy still will have sperm in his penis. The proper way to do the pull out method is to pull out then stop. Give it a few hours if you want to keep going. Some guys even pre-cum so you could still get pregnant.
You cannot get pregnant from stray sperm in swimming pools or stray sperm in general. Sperm is very delicate and can be destroyed by water or sometimes even air, even bacteria in the vagina itself can kill sperm. Unless you use artificial insemination, a penis and a vagina together are necessary to make a baby.
yes
No, if you did not remove your jeans, then it is highly unlikely that you will become pregnant, even if sperm got on your jeans in the vicinity of your inner thigh.
Any amount of sperm can make a woman pregnant. Even one little tiny sperm by itself can get the job done. The chances are lowered greatly though but it is still very very possible.
You can, even though the chances are reduced.
yes...yes a girl can the sperm can b ejaculated enough to get her pregnant even with out penetration to the vagina
