I find that the single most important thing that interests me in a person is the ability to have long, wide-ranging conversations. I love talking to people who are interested in just about everything, even though everything may not be an interest (if that makes sense).
I am more of a thinker thank a doer.
I am an engineer both by my nature and by profession, and I love letting my mind flow from topic to topic building fascinating webs of ideas. Not in the ADD sense but rather simply in the sense of letting thought wander like a leaf in the wind.
I am an introvert. Spending time with friends brings me joy, but quiet is how I recharge.
When it comes to developing an interest in a woman, it takes time. That interest forms as friendship and trust form. I've really never had serious interest without the other two.
I have very little dating experience, so I'm really not sure exactly what I'm looking for. I suppose at this point I'm mostly hoping to find someone who likes to talk and cuddle. :-)
Guess that's it for now. We'll see what else I add...
