Seriously? Why does anyone think that sending unsolicited nude pics is EVER a good idea?! I honestly thought it was a phenomenon that only females were victims of. Perhaps that is only because dudes usually don't complain about a free look. But apparently even chicks think that forgoing communication and diving directly into flashing is a preferred & affective means of flirting.
My tip for you. Don't do it. Flashing your body in leau of talking only communicates that you have no personality or character worth sharing.
