SUBREDDIT: r/relationships
TITLE: I (26F) am jealous of my boyfriend's (28M) ex girlfriends' bodies and it's driving me crazy.
POST: My boyfriend is an attractive guy. Needless to say, all his ex girlfriends and flings are flippin' gorgeous with amazing bodies. One of his ex girlfriends was actually a model for Sports Illustrated, so yeah. I am a fit girl and I am attractive, but I do not compare to these girls. For one thing, my boobs are much smaller. I can say, though, that my personality kicks all of their asses, so I've got that going for me. Haha :-/

I've never felt insecure in any of my relationships until now and it's driving me crazy. I haven't actually mentioned my insecurities to my boyfriend because I know how it will come across and I know that sort of thing can be super unattractive. I guess I'm just wondering if there is any way I can get over this or am I just doomed with these terrible thoughts forever? Does anybody have any tips n' tricks for me?
TL;DR: 
My insecurities are getting the best of me when I compare myself to my boyfriend's beautiful ex girlfriends/flings.
