I hate shaving my legs and armpits so much. I never shave my armpits except for the one time last summer I went to a water park with my work and did the board short/rash guard thing with a tight Nike sports bra underneath (I'm small chested and the tight sports bras make me flat enough to be comfortable in most clothes). I shaved my pits just in case they made me take off my rash guard.
I do shave my legs, though, as much as I hate it. I have to wear shorts for work all summer. Well, I could chose to wear pants, but I'm running around outside all day, and it gets hot, so I wear shorts. Since at work I'm more andro than anything else (female pronouns, but no one really treats me like a "girl" because I'm so masculine) and I don't want to offend anyone since I'm there to rock at my job, not make a statement, so I just shave them. In the winter I let them grow, though.
