Hi.
Since you say that you feel "very weird" after dreaming about this, I presume that you don't have many waking thoughts about being with both a man and a woman. Or perhaps you have the thoughts but have pushed them away.
It's always up to interpretation what dreams "mean." Many psychologists, including hugely famous ones like Freud have debated the nature of dreams and there is no agreement as to how they relate to a person's life exactly.
Because these dreams are recurring, however, they may indicate a hidden anxiety or desire that you may have. Most of the time, if people search deep enough, when thinking about the dream they will discover the root of the imagery.
Just remember that dreams cannot make you to do anything that you don't want to do. They may merely be giving you information about what's going on behind your brow bone. So don't feel pressured by your dreams, sit and think about them calmly.
Take care.
