I taken to wearing women's legging exclusively when I go to the gym. They feel so much better and they make my butt feel great.
Oh wow, do people stare at you? How tight are your leggings? Does the front bulge out? I have some white leggings, and I'd like to wear them at the gym, but my gym is small and there are just a lot of people at the gym. So guys, how do you do it? Do you just say 'fuck it' and wear leggings at the gym, or do you wear leggings when no one is around?
I catch a couple people staring but I don't really care. My bulge is not very apparent due to the types of thongs I wear underneath my leggings. I wear Hanes X-Temp thongs that are women's thongs under my leggings and because they are meant for women, they are tighter in the front and keep things flattened. I like those thongs for working out because they breathe, are moisture wicking, and stretch enough to keep my "stuff" contained. I stick to dark colors because that not only hides the bulge better, but also less of a chance they are see-through.
When it comes to my gym attire, I usually rock what is comfortable. The riskiest I will get is wearing only a thong into the steam room or sauna. I normally go to the gym pretty late at night, so I take advantage of having the place to myself and thong out more freely.
