Both Yin and Yang are needed for our sex lives to flourish. Where do you fall on the spectrum? Partners in relationships can both be dominant in one type, but we most often see opposites attract.
When Yang dominates a relationship, sex can be passionate at first, but eventually, this gives way to dissatisfaction as the emotional component of the relationship is ignored. You might see resentment and frustration manifest toward the Yin partner and an inability to be vulnerable.
On the other hand, when there's too much Yin, the relationship is sexless. If there is no initiator, there is no sex. When sex does occur, it's described as "boring" as Yin lacks creativity and sensuality.
Combining Yin and Yang in the bedroom requires honoring our evolving natures. The balance of Yin and Yang is ever-changing because people are ever-changing. In the bedroom, that means honoring and asking, “Where am I now? Where is my partner now? What do I want now?”
