Mr. Answer Man says: Let's turn the question around for a moment: How would it make you feel to look down and see long red nails on your hands? The fact is that if they give you a secret thrill, your overall demeanor will be sexier, which is, well, a turn-on. (The converse is also true: If long red nails would make you feel like you had 10 thumbs, you'll come across kind of klutzy.)
This is also a phase-of-life issue. If you're single and long red nails are your thing, then wear 'em loud and wear 'em proud; you want to meet the guy who crossed the room to talk to you because of your nails. On the other hand, if you're taken and looking for a way to spice things up, try this simple experiment: Buy a pack of Lee press-on nails, put them on, and go make a blatant pass at your honey. You'll get your answer.
Do you think Mr. Answer Man is right?
