9. When your skin is flushed from exertion.
Men rarely see women sweat these days, other than when they play sports or exercise. Men find a slight sheen of perspiration on your skin, especially around the back of your neck, extremely sexy. When you arrive at your date panting and with moisture on your skin, he may find your sexuality amplified. But don’t assume that all sweat is sexy and charming. You do not need to make yourself sweat intentionally.
