A male condom is placed on a man's erect penis. A female condom is inserted inside the woman's vagina.
You may mean a "condom". This is a word that refers to protection against getting a woman pregnant. A man may wear a condom on his penis when having sex. Most condoms are made of latex, but some are made of lambskin. A condom can also prevents some diseases: there are studies which show that using a condom can prevent the spread of the AIDS virus, for example.
It is the same if a man climaxes inside a woman other than in her vagina. If he was receiving oral sex, either he's spurted into the other person's mouth or into a condom. If it was without a condom, the recipient can spit it out or swallow it. If he was performing anal sex, he's ejaculated into the other's anus, either into a condom, or if not using a condom, then it will drool out.
The condom is for the male and can only be worn on the penis. The woman can use a barrier if she so desires. It is worth knowing 1 in 7 condoms fail.
Condoms don't prevent pregnancy by killing sperm, they prevent pregnancy by capturing sperm cells when the man ejaculates. Once a man ejaculates in a woman's vagina without a condom there is nothing a condom can retroactively do to prevent pregnancy. Best to put on a condom before intercourse. If you have ejaculated in a woman the best way to prevent pregnancy is the "morning after pill". It's a dose of hormones that can prevent ovulation.

(Sometimes it stay behind if the man does not pull out after ejaculation, but this is not common) If you have latex allergy or rubber allergy and the condom is made out of what you are allergic to, then this can cause inflammation leading to severe itchiness or even pain. If having sex with a man wearing a condom and you get problems, then change to another type of condom next time. There are condoms made that are not considered allergenic. Normally the woman cannot tell between a regular penis and one that is covered with a condom. There should be no difference in the sensation to a woman.
Women have sex cells called eggs, and men have sex cells called sperm. When a woman has unprotected sex with a man (ie she's not taking Birth Control and the man isn't using a condom) and one of the man's sperm cells enters the woman's egg, a fetus forms and the woman becomes pregnant. Some people have fertility issues, meaning that it's difficult or impossible for them to have a baby naturally. There are treatments these people can use to increase the chance of pregnancy.
