Simone on Sex, Lies and Dating has a great list of what is and isn't sexy. What is: a natural smile, taking care of yourself, smart with interesting things to say, chutzah and kindness. From my perspective at least, she totally nailed it.
Sirens has a series called Peace Talks, one between single and married friends, another between a mom and a child-free friend (hat tip to Simone). Lots of common sense here, and very little judgment.
Wendy from First Person Singular asks a great question: if rejection "isn't about you", then what about when there is attraction and love? Her friend says "It's not about you then, either." Hard to refute the logic but sure makes me think...
Liz Rizzo feels she has lost her appetite for love and dating. "Like someone new could be the most beautiful banana split ever, with whipped cream and cherries and nuts, and when confronted with this person I would remember how much I love banana splits, maybe even want to still love banana splits, but be left with absolutely no stomach for one." I really like this metaphor - when you say you're not hungry, no one accuses you of being anti-food or resentful of others who have food or of being in denial about how much you actually want to eat.
