i m in US , for many many years... never heard/or seen underarm hair shaved considerd gay. u must be in gay community :P just kidding.
Are you a Muslim male or a sardar jee. Sardar jee do not shave any hair. Muslim male are supposed to follow the tradition of our Holy Prophet(SAW) and shave our under arm hair and pubic hair on a regular basis. It is not mandatory but as I said a tradition of our Holy Prophet(SAW).
