I really don't like sex , i really don't like to see girls body , i just feel disgusting when i see naked body,?

Don't rush it: Different people react to different sexual stimuli and situations very differently. I don't know your gender, or what your sexual orientation are, or whether you feel uncomfortable with your own body as well as those of others. You can talk with a counselor your physician can recommend. What I hope is that you'll seek to make friends and eventually fall in love. Anybody can become beautiful.
