I have a ton of issues, so much so that when men tell me I'm beautiful or I have a great this or a nice that, I say thanks but secretly do the roll my eyes thing as I think to myself that they are lying through their teeth. I don't know why I see myself as a certain way that others don't see, but I'm glad they don't see me the way I do or I'd be in really bad mental health with regards to my body image.
I'm very self conscious about a lot of things on my body. Pretty much all of those you mention. I'm definitely not a size 0. I have stretch marks, sometimes I have acne, cellulite, and I don't have scarred boobs but I do have a scar on my leg from an accident I was in a few years back that caused me to almost lose my leg. I almost never wear skirts or dresses because of it. BUT I took pictures and put them in my gallery anyway. It feels kind of self liberating. I haven't received a bad comment yet and if I did, I think in general it would just make that person look more like an ass than anything else. It's simple, if you don't like what you see, don't post a comment, just move on.
The only person you have to please is yourself. Once you do that, everything else comes naturally.
We all have our insecurities, that's what makes us human. If we didn't, we'd be a soulless bunch for sure, just drones who don't care what they think of themselves let alone other people. I believe some insecurities make us who we are as people. You really think about things and it builds your morals. If you wouldn't like someone to talk about your (insert body part here) that way why would you talk about someone else's like that?
We are not super models, most of us don't pretend to be. Even celebrities comment on their own photos. Just today I saw on tv where they showed a celebrity a cover of herself on a magazine and the first words out of her mouth were "Look how blonde they made me and look how big my boobs are, my boobs aren't really that big."
Anyway, if you don't want to go as far as some women do on this site concerning pictures, then don't. Do what makes you feel comfortable. None of my pictures are completely nude. In fact, everything is strategically covered up in a suggestive manner. Though my boyfriend would like me to show myself off more, I feel like the things I let him see and experience are gifts to him, an element of my being that relatively few people have ever really seen and I'd like to keep it that way. So I show off a little of this and a little of that but not 100% of anything.
Just do what you feel comfortable with. Don't let anyone pressure you. Your body is your body you have the final say on who sees what and how much.
