Virgo and Sagittarius are both thoughtful souls and they love having long and in-depth conversations with each other. Philosophy is a shared interest and if there's red wine involved they'll be talking all night. Both are excited by travel, activism, politics, and helping people in need. Unfortunately, it's these interests that connect their minds that can often drive them apart physically. These signs are both independent adventure seekers who tend to put their partner second to this interest.
In addition to the problems above, Virgo and Sagittarius are a mismatch in the bedroom, too. Virgo loves to take things slowly and sensually, always providing a giving experience. Sagittarius is a lot more fast and furious, which leaves them out of sync with each other sexually. Virgo is often left disappointed, which can fester and manifest in the form of passive aggressiveness.
