Makeup is for Girls
Traditionally we have been taught to believe that makeup is for girls and women, and that if you are a man who uses makeup then your sexuality should be brought into question. Obviously, this way of thinking is backward and wrong, if you feel makeup would help you be more confident in the world then wear as much as you want.
The film industry has done a great job of normalizing makeup for men. They use it in movies to enhance special effects or cover up tattoos and blemishes. They also use it on their male actors during movie premieres and press junkets.
