The man with the lowest sex drive I know (he's anti-sex, basically), a guy I used to think of as my brother, is a Virgo man with Sag rising, and Gemini Mars on his Desc, squaring Venus and Jupiter, and opposing his Moon. He is utterly disturbed when he gets to find out I had sexual encounters, is annoyed by nudity, etc.

But you haven't filled in the most pertinent details yet.

Is he rich? Single? Handy around the house? Clean?

Details! 😉

Ah ah ah, well... he's a Virgo! (And a German one at that...) He dies inside if his house isn't compulsively tidy and organized. However, he hates money and doesn't want to get rich.
