It isn't just male mode, I have just never felt comfortable in dressing rooms, always feel like someone is watching me on some camera. Heck I never even liked changing in the locker rooms in high school, I would wear my sports uniform under my normal school uniform and just take the shirt off for sport revealing my sports uniform top and then chuck the regular uniform shirt back on over it after..(was a b*tch in summer) I have always been self conscious I guess.
