Is this cynical or am I doing them a favour?

In a social situation, I treat women who I meet in a friendly way - buy drinks, jokes, chat, etc and I always leave alone. I don't want to satisfy them sexually. Nope, I am not gay. No law compels me to gratify women - if they do it with someone else after I have left the bar or restarurant, that's fine, but not me. I am masculine 'down there'. I am being cynical or independent?
