Not into men anymore

I've had low self esteem issues with my body for years. On a serious tip, I do enjoy the way I look, my health etc however when it comes to sex, I'm not into it. I've tried to be sexy, initiate sex but all have failed. The men in my life would say they love sexy lingerie and other things that enhances a womans body but I tried everything and they all failed! I don't think that I'm attractive when it comes to men. I love my look, my poise class and everything but to these men I'm just a canvass. Good to look at but don't touch me, why????because all he's gonna do is break me.
