ty934,
Your nipple has small muscles which cause it to tighten up. This occurs when you are cold or when you pinch them. Most men with mild gyne say that their chests look normal when this occurs. I know mine did before I got the surgery in October.
Looks like you may have a mild case of gyne. The picture is not great and it's upside down. You may have a small amount of gland tissue present. This of course can only be diagnosed by a surgeon with extensive experience in Gynecomastia Surgery. I would suggest asking one of the surgeons listed on this site.
Best of luck with whatever you decide!
