Well, yeah the skirt idea was good. But wasn't your question more directed toward sex? Why do you need tips - if you know what it used to be like and if you're aware that it was like a routine, then if you see yourself falling into that pattern - pull away from it and quickly try something else. You're the one in control, we don't know how your nights going to pan out, be adventurous.
To love is to suffer. To avoid suffering, one must not love; but then one suffers from not loving. Therefore, to love is to suffer, not to love is to suffer, to suffer is to suffer. To be happy is to love; to be happy then is to suffer, but suffering makes one unhappy; therefore to be unhappy one must love or love to suffer or suffer from too much happiness. I hope you're getting this down.
