Aries Aries tend to be fearless, intense, and emotionally invested people. An Aries will speak out and make adjustments (such as cutting someone off) if a relationship isn't working for them or if someone is getting on their nerves.
Since Aries wants to be physically attracted to their partner constantly, they place a lot of strain on their relationships. They may even go for it elsewhere if they aren't getting it from their spouse, especially if they aren't sexually attracted to them.
Leo Leos are very interested in romantic encounters of the flesh. They are extremely romantic and passionate.
They believe that a lack of sexual chemistry is the single most decisive factor in the success or failure of a relationship.
Scorpio When it comes to love, Scorpios are notorious for being even more passionate than usual. Combine this ferocious vigor with their powerful sensuality.
Sometimes they don't trust them enough, or aren't ready to reveal the aspects of themselves that they (attempt to) conceal, so they keep things casual with a purely sexual, no-strings-attached relationship.
