Well
Pregnancy occurs when a male's sperm burrows into a female egg (fertilisation). The sperm is one of millions that are contained in a man's semen (the liquid produced when a man ejaculates or 'comes'). The egg is released from one of the woman's ovaries (ovulation) between 12-15 days before her next period.
Millions of sperm are also found in the liquid produced by the penis as soon as it is erect (hard). This means that a man doesn't have to ejaculate for pregnancy to occur.
Sperm enter the woman's body through the vagina, before making their way through the cervix and womb to the fallopian tubes where the egg is fertilised.
It is possible for a woman to get pregnant without having sexual intercourse (penetration), if there is a chance of any sperm getting into the vagina. For example, a woman can get pregnant if there is sperm on her fingers and she puts them into her vagina.
However, the chances of you becoming pregnant in this way are very small because sperm can only live for a very short period of time when outside of the human body (a few minutes if left to dry out, or a few hours if wet).
It would also be possible for pregnancy to happen if the man ejaculates close to the entrance of the vagina, or if his erect penis comes into contact with his partner's body near the vagina.
Again, the chances of you getting pregnant in this way are much smaller than if you were to have penetrative sex. However, it's important to be aware that, in some cases, getting pregnant in this way is a possibility.
If you think that sperm could come in contact with the vagina in any way, the best way to avoid pregnancy is to use contraception. Only condoms can provide protection against both pregnancy and sexually transmitted infections (STIs).
If you use a condom it should be put on the penis as soon as it is erect to prevent any sperm from coming into contact with the vagina.
