Trusting in Fate that you'll meet again is the avenue least likely to provide satisfaction. I'm not into one-night stands, or just casual sex. I do masturbate, but I want a real man. Sorry, can't do. When a person is not getting what she wants, she can work smarter and harder toward achieving it, modify her goal so that it's more easily attainable, or do without until the Universe provides.
Nobody needs sex.
You might miss orgasms, so continue doing it yourself. You might miss full body touch, so go dancing or get a massage. Flirt or ask others for compliments. Get a pet or do volunteer work with the truly needy. My problem has a long history and can be summed up with the latest interlude in domestic conflict.
