Drunk SO

Seeing someone drunk is a big turn off for me. Maybe it's because I've never been drunk before, I rarely drink and I've had people around me suffer because of alcohol. My SO doesn't go out much but when he does I just hate thinking he's going to get drunk. He's told me he's never been drunk since we've been together but I don't really believe him. Do you mind if your SO gets drunk (for the most part)? I don't mean everyday because that's obviously a big no-no. Does it depend on who he's with and where he is? Feel free to comment.
