I guess the way these "self pics" come to be is following one of several scenarios:
>> Girl is getting dressed and poofed-up for a date, looks in the mirror, and says to herself, "Hey, I look HOT. I should take a picture of myself...!" or
>> Girl wants to send something erotic to her boyfriend, so "I'll send you a photo of me naked!" or
>> Girl thinks, "I'm hot naked and nobody knows it; I'll take a picture and post it so everyone knows." or
>> Girl thinks, "I'm hot now but am getting married/having kids and won't be hot for much longer, so I think I'll keep a record of my hotness."
Something about all this that's, well, ----hot!
