noun
young man inexperienced with women; male virgin
Refers to a young man who has not had sexual experience with women. Often used in a somewhat old-fashioned or literary context. Compare with 生娘 (きむすめ) for a female equivalent.
See also: 生娘
彼はまだ生息子で、女性と付き合ったことがない。
He is still a young man inexperienced with women and has never dated anyone.
童貞 is a more common and modern term for a male virgin, while 生息子 has a more literary or old-fashioned nuance.
Compound of 生 (き, 'pure, unadulterated') and 息子 (むすこ, 'son, young man'). The exact historical derivation is uncertain, but the term follows a pattern similar to 生娘 (きむすめ).
