It’s normal for both straight and gay guys to have erections when they are naked which can be embarrassing when it happens in a locker room.  This usually stops when you become more comfortable with being nude in front of others. In the meantime, here are some suggestions you can try.

• Change in a private area such as the bathroom stall.
• Consider wearing your gym clothes underneath your regular clothes on gym days so you don’t have to change.
• Many workout clothes can double as casual clothing so you don’t have to change.
• Try to think of something else that isn’t sexual.
• ​Be patient! This is very common and almost always goes away with time.
