Observations
Sun people are naturals at stroking someone's Ego. A Venus person could get the ick if Sun tried to stroke theirs but it could low-key be a gateway to a lasting friendship. Krittika is usually good at stroking kids Egos, Uttara Phalguni is good at stroking their coworkers or business partners, Uttara Ashada is good at stroking their lover's Ego.
A Sun-Sun Ego stroking could lead to both being blushing messes.
Mercury people are often times naturals at the art of sex, but intimacy may be something they'll withhold until they feel safe. And often times they'll want intimacy with people close to them. They'll hold friend's hands or stroke their face. Same with family, they don't want to be told they're too old to sit on their parent's laps. They'll usually give intimacy to their lover if their lover gives it first.
If Mercury people don't have that grounding of intimacy growing up, they may view the intimacy they see in others as weird or too much. Revati usually needs intimacy with their friends, Jyestha usually needs self intimacy(they can sometimes solo poly), and Ashlesha needs intimacy from family.
