I'm feeling down about my image..how do I not?

[Jacinta C]

I work with this girl and we get along really well.we are like friends she is really nice.she is a porn star and she is nice looking.she's tiny and has had her breasts enlarged.I'm happy with my breasts,some men I work with have been commenting on me saying my bodies no good.I am slim,I'm not large but it just really gets to me.I feel like I am always being compared to my friend by them.I feel like they've seen her naked but they've never seen me naked so what gives them the right.not just that but it's work.I'm not a porn star but guys have told me before they love my breasts,rear end and so on.why does this bother me so much??
