Confidence without arrogance, a sense of humor and the ability to flirt. I love attentive interlocutors who notice details, make sincere compliments and are able to intrigue with conversation. It is especially attractive when a person knows what he wants, but leaves room for my desires.
Turn offs:
Rudeness, obsession and demands from the very first minutes. I don't like it when they start an acquaintance with orders, rush things, or perceive my attention as a duty. Pressure, insults, and attempts to argue with my "no" immediately spoil the mood.
