Is it hypocritical to wear extremely sexy spandex for exercising even if you are a virgin and have no intention of becoming sexually active until you are married?

Yes. Wear what you want, but when you are a virgin or even a girl that knows she isn't going to have sex with a male, then dressing sexy is called "advertizing." If you don't want the wrong type of attention then tone down your dress code. You can wear some spandex (say the leggings) but wear something not quite so tight on top. There are cute tops with part of the mid-drift showing. You are still in the fashion mode if you are a teenager and won't feel left out as far as dress code. Be respectful of your body, mind and soul because if you don't, no one else will be and you could lose a lot of respect from people you care about. All young men want sex, but they sure have little respect for those girls that "put out" or act too sexy. It's always been that way for as long as I can remember.
