<human>: Can you provide a brief overview of the text?

This isn't really an issue and there is actually no pressure from my boyfriend AT ALL - but is it weird that I adamantly don't want to see what his ex looks like?  
I've been in a serious relationship (my first!) with my awesome SO for almost 2 years.  We moved in together mid last year and are in it for the long run.  
Regarding his ex, I'm open to talking to him about her.  I actually raise the topic most of the time (if not all).  I asked how she looked like and he told me that she was hot and he was initially interested because of lust.  He says he was young and now sees personality as more important, and I believe him.  He loves me, always makes me feel loved as best as he can, and we are the best of friends.  
But I have self-esteem issues.  I feel inferior to pretty girls and, knowing that his ex is the type of hot/popular girl I never could/can be, well, I can put that aside.  I just am afraid of putting a face to the person because if I will have that to constantly compare myself to when I feel particularly down.  Also, if I see a girl who looks like her, I'd probably feel paranoid that he'd like her more than me.  (Yes, yes, I know it's personality and compatibility that makes a successful relationship...and we make an awesome couple.  But I can't help that the insecurity about my looks pops up now and then).

My SO doesn't mind either way whether I want to see or not.  He has offered to show me her fb profile but I declined.  I definitely don't worry or obsess about his ex at all.  She's in his past, has been married for years, and far away.  We both have a rule about not contacting exes.
Is this understandable and do any of you feel the same way?
