I use lipstick, eyeshadow, eyeliner, nail polish, and certain kinds of tights/stockings. All of these I use to some degree to change how I look to suit how I feel, which helps me quite a bit at times.
I also occasionally pick up feminine scented soaps or items of a similar nature. This is because most scents associated with females are often more gentle. I do have a sensitive nose, and don't like strong smelling products. Sometimes even a hair care product or two, even though I loath doing anything with my short hair besides cleaning it or combing/brushing it.
Although I personally identify myself as both genders more often than not, there are enough times in my life that I simply must play along with only one role, no matter how masculine or feminine I may feel at any given moment, so for the nature of this poll, I went with the obvious choice of what I use less of.
