when the question "nudes?" fail, you turn to a different question, "partials?". Partials meaning to get pictures of them partially naked. Could consist of them being in their bra & underwear, underwear & covering their boobs, or some kind of "tease shot".
Some girl didn't want to send me nudes, so I asked her for some partials. They were more satisfying then not getting anything at all.
Guy: Hey baby you wanna send me some nudes?
Girl: I don't think so.
Guy: How about you send me some partials?
Girl: I'll think about it.
Partials OR GTFO :D
