Sexual intercourse is sex with penetration of the vagina or anus by a hard penis.
Penetration of the vagina
A man who is aroused can get an erection. The penis swells with blood. It gets bigger and harder and it rises up.
A woman who is aroused gets a wet vagina. This helps the penis to enter the vagina.
The woman can get pregnant only if:
- the man’s semen enters the woman’s vagina and uterus and if
- the woman is in her fertile days of the month.
If you do not have a desire to have children at the moment, use contraception.
