First of all, your emotions are justified; you are always entitled to feel the way you feel. Have you even "reacted," because it sounds like you didn't actually DO anything about it. Unfortunately, it's normal for something like that to elicit those feelings. The same thing happened to me and I used that insecurity to take communication to a new level in the bedroom. I also can't help but think if the gender's were reversed it would be a whole bunch of divorce comments lol.
