How to look more masculine without a beard?

beard growth is genetic, so not all guys get beards or have full ones if they do grow whiskers. Can come in at any time-- I was shaving a full beard at 13, my friend did not have much of anything to shave at 18. Still doesn't. So no way to stimulate beard growth at all. If you are normally horny and sexually aroused, then your testosterone levels are probably fine. So that would not be an issue. You can bulk up your upper body with workouts and that will make you look more masculine, plus exercising gives you a natural confidence and sense of well being. So consider starting a good work out routine that includes running/jogging or walking, building up to about 4-5 miles a day-- and begin doing upper body workouts too. Might consider joining a gym where trainers or other guys there can show you how to use the equipment properly.

Show us a picture of yourself, maybe we can give you better option and opinions.

Stand tall, roll your shoulders back and have some confidence. Also, look people right in the eyes when you talk to them. And say less.

That will work.

Let your hair grow a little longer and get a mature hair cut. Hair style can make a big difference. Buy more mature looking clothes, clothes that fit and look masculine.

Masculinity is an inherent trait. Either you are masculine, or you're not. You can't act masculine.

If you have a feminine nature, you can work at being less feminine, but you can't pretend to be masculine.
