Why does dad put his wee-wee in mom's don-don?

This question refers to a biological process related to human reproduction. When a man and a woman engage in sexual intercourse, the man's penis (often playfully referred to as "wee-wee") enters the woman's vagina (sometimes called "don-don"). This act can lead to conception, where a sperm fertilizes an egg, resulting in pregnancy. It's important to approach this topic with sensitivity and provide age-appropriate explanations.
