I understand, comrade. Sometimes the flame needs a little encouragement to burn brighter. I've been there. I suggest you try new fantasies, surprise your partner with unexpected gestures or even try yourself in different places to rekindle the flame. It also helps to watch porn. The key is open communication; sharing desires and needs can lead to greater understanding. Remember that intimacy grows when there is room for novelty. I, for one, have turned simple moments into unforgettable experiences. Try it and you'll see the difference.
