Have you ever experienced positive peer pressure?

Positive peer pressure is the only way I can think to explain it. When I am around certain people, I feel like I can only go so far. It’s not that I feel like I can’t be myself around these people, but that they, to some extent, look up to me as one that can have fun without doing anything that could be harmful.
For example, I was out with some friends from high school the other night and we had some alcohol. I drank one drink, then went to grab another one, came back, and my old best friend gave me a “look”. She knows that I’ve never been drunk before, but I felt compelled to announce it to the whole room that I don’t drink to get drunk.
