I currently work in a lingerie store after having spent a fair amount of time in 'professional' environments.
I'm less tired coming home from 8 hours on my feet dealing with the public than I was in professional settings. I don't have to hide everything about myself and my background (I'm a first-generation college student with a poorish upbringing) or constantly worry about what all my interactions with colleagues mean for my 'career'.
I will say my class background is more of an issue than my sex/sexuality, but my sex was way more of a problem in my teens and early 20s. The interesting thing is that being a techy child was fine, being a techy teenage/20 something girl SUCKED, and being a techy 30 something woman is fine.
