When I try to describe my transman boyfriend to my family, I usually say that he was born female but now he looks, acts, and smells like any other man. But really, what works best is for them just to meet him.

A trans man is a man sexed as "female" at birth, who identifies and lives as a man.

A trans man may or may not take testosterone supplements or have reconstructive surgery, depending on individual circumstances, health, desires, and finances.
