What, in your mind, is sexy? It can be in regards to attraction, appeal, etc to a person, thing and such.
Here's mine, not limited to of course, and in no particular order:
Intelligence, strength (physical and emotional), humor, red and gold (!! XD!!), emotional maturity juxtaposed with a silly side, navy blue and beige, uniforms, knives, creativity, compassion, fast learners, Italian (the language), and um... eating ice cream off people :)
So, let's have yours!
