I'd love to say I'm listening, but if I'm honest most of the time I'm waiting to talk or waiting for her to simply stop talking!
For me it's confidence over every else. Someone who knows their own mind and knows what they want from life.
You're obviously generalising from your own negative experiences but for me I would love a relationship where both partners can be 100% honest with each other, the honesty helps build the trust that any relationship needs.
I would have to agree with the other posts and say that my ideal 'one nighter' would be with someone who was willing to experiment and to use the opportunity to explore all the things we want to do but never ask of our partners.
