Being confident communicates that you are a high-value person. No one wants to be with a person who is tentative, who begs, or indirectly maneuvers or manipulates to get what they want.
Yet, in this modern world of negotiated relationships, of putting the other person first, of thinking about their needs, the passion and desire leeches out of our dynamic.
So, if you want more, tell her. Or tell him. Use your words. Your partner is not a mind reader, and if you don’t ask for what you’re not getting, well, you’re sure the hell a lot less likely to get it.
Try it. “I need more sex.” Or “I need better sex.” If you’re afraid of your partner’s likely reaction, play it out in your mind, and how you’ll remain calm and focused. But you are important. And you have a right to get the sex you need. Ask for it.
