@TogetherAlone,
Please don't torment yourself about your feelings. It's useless to do so and injures you. Your feelings and desires are your own. Life is all about sharing them with intimate others. You don't share your feelings with mere strangers. I, too, have those feelings you speak of, but I'm in my forties and enjoy them. There is nothing wrong with you, believe me. Loneliness and isolation are what's wrong with people. The women whom I am intimate with please me in many ways that I am so grateful for; the men, too. There is no deeper thing on this earth than a love relation, no matter with who, that lasts. Mine are not exclusive either. As things have turned out for me, "exclusive love relations" don't suit either me or the people I want to be close to me. Make your own life and trust yourself: follow your own thoughts and desires and make your own judgments.
