Human penis
A man can put a condom on his penis to prevent semen from entering the female's reproductive system. A condom is very thin, so having sex still feels good. It is normally made of latex. If used correctly, a condom usually stops the woman from getting pregnant and having a baby. The condom also lowers the chance of getting a sexually transmitted infection from the sexual partner or giving a sexually transmitted infection to the sexual partner. While condoms are most commonly used during vaginal sex, a condom can also be used during oral sex, anal sex, and masturbation.
