I wear jeans because they are comfortable, durable and most of all - functional. As a VERY ADHD Aspie who is TERRIBLE about keeping track of stuff, I can't really carry a purse or a bag - I lose them daily. I have found that if it is strapped to my butt (in pockets or on belt), I keep MUCH better track of all my essentials - flashlight, leatherman, keys, wallet, money, etc., etc.
Yes, everyone takes me for a lez because I carry a wallet and no purse, but too @#$%$#% bad. It works for me. Get over it.
I wouldn't think you're a lesbian, its practical. My dad caries a coin purse and a wallet. But don't put your stuff in you back pocket it is easy to nick, front pocket is safer.
