Leo is a Fire Sign, and needs action to stay motivated. You also need direct communication, and don't like to beat around the bush, or guess what someone's thinking.
How are you supposed to get anything done if you can't express your innermost feelings? How will you know where you stand if your mate doesn't tell you? You don't need to worry or be aggressively demanding.
Every sign has a different communication style. Making suggestions, and even developing a playful banter with your partner shows them that you're not to be feared but adored.
