I feel like I recognize this somewhat. I've been so socially phobic all my life that I think I sometimes lack the experience to know what is "too much information" when I do let down the guard.

I think the best favor we can do ourselves is to try and learn from the responses we get. Maybe be a little less forthcoming. Tattinka, maybe cultivate a bit more of an air of mystery and let the person you are with work harder to draw you out. Then don't quite share everything that you may be burning to share. There comes a point in a close relationship where people do share a lot, but that point is not reached on the 2nd date. I haven't got it all figured out myself, but I'm working on it.
