I have a kind of not mature voice when I speak normal. I was talking with a friend about trp and being alpha and stuff. He said without realizing that my voice gives away that I am not an alpha. That got me worried because I am aware that my voice can get more pitched. I can speak in a deep voice but it doesn't come natural from inside so i have to force myself. Also, I realized lately that when the social interactions are under my control, then I can keep talking in a deep voice but as soon as I am not my voice gets to its normal state. Anybody have experienced this kind of stuff? Any advice?

P.S. : its not like I have a girly voice, just not manly enough
