hi doc,

I m male, 25.
I am basically tall and lean in nature, small face and less facial hair. My problem is i look like a 15 year old boy. All my family members look very bold and every one has good mush and bush, even my younger brothers too. Every one is making fun of my appearance. I am really frustrated with my external appearance. My old friends told me that i have no difference in these past 5 years. So i am avoiding them. I have a normal size male organ and don't have any sexual problems.My marriage is fixed and will be getting married within an year.
I worry that is there any deficiency of vitamins or proteins or another hormones ( like testosteron) for me. Do i need to conduct any tests ?
I have a small face and my facial hairs are very light and thin as like a boy. Can i have any tablets for that ?
I am concentrating in body building now, going to gymnasium. Can i take any mass gainer protein powders ( like Whey protein) ? can u suggest a brand?
I masturbate every night (sometimes two) and feels tired next morning . Is this a problem ? how can i control this ?
Please answer me all and i would like to hear is these are common problems, to an extent ?
