How do you tell a girl to send you a pic?

This is to anyone that ask this question:Well just don't ask them to because that is stupid I us to send pics to guys and now I wish I haven't and even though that girl/boy don't have a boyfriend or even if she dose you don't wont to affect that relationship much less her/his up coming ones so I ask of you please do not seen or even ask guys/girls to send pics and this is to both and not only that but just don't send any pics in less they are descent ones. But that is just a suggestion you don't have to Liston but I hope this helps you out in any kind of way.
