Because of characteristics that I can't control (penis size, facial attractiveness, etc...) I constantly feel inadequate and not "worthy" to have sex with a woman, almost like I wouldn't understand why a woman would be turned on by me. If I see a good looking girl pass, I can't imagine her actually consenting to being in bed with me and enjoying the experience. I also constantly compare myself to other guys I pass, in terms of looks and height/etc. I know this thinking is very toxic and not helpful, and I would really like to get rid of it. Any help in doing that?
