Quotation zu Mischlej 18:22

Every man is obligated to marry a woman in order to be fruitful, and to multiply and anyone who doesn't engage in being fruitful and multiplying is as if he spills blood, and lessens the appearance, and causes the divine presence to depart from Israel. Rem"a: He who does not marry is not allowed to make a blessing or to engage in Torah etc. and he is not called a man, and when he marries a woman, his sins are cast into doubt, as it is said: "One who has found a wife has found goodness and obtains favor in the eyes of God." (Proverbs 18:22)
