Used to, but even then to a far lesser degree than many here. I'd go to parties and social things, but once I got there often kind of hide in the corner and wish someone would come and talk to me. I'm a lot better now. I spent 6 months working in retail, which was definitely a "what doesn't kill you, makes you stronger," proposition. It forced me to learn to carry a conversation, to look people in the eye, to deal with strangers, answer the phone immediately, and look and sound assertive even if I didn't really feel that way. I came out of it far, far better able to deal with social situations, and I'm glad I did it, although it was utter hell in the beginning. It helped that I was working in a comic/hobby shop, and my obsession du jour at the time was Star Trek Collectible Card Game cards, so I had a common interest I could share with a lot of people coming in.
I still, I think, find interactions difficult on a number of levels (and talking in the last few days, my wife says I miss a lot of social cues that I had thought I was reading correctly, c'est la vie), but I don't shy away from them, and I don't fear them per se, although oftentimes I wouldn't necessarily have sought out social situations, at least with people I don't know.
