SH!T!!!!! Just realized this thread is a year old and this (most likely) bot above me upped it! Oh well...
"Convince" should not be in your vocabulary.... Influence is better as it's normally under the radar...
When you try to convince someone to do something - they become the prize. Whatever it is you want from them becomes the prize. That's not a good thing.
So... How is it done? Let's say you want her to give you a backrub... Normal guy:
Guy: Honey, can you give me a backrub?
Woman: Why should I? (= "tell me how much of a prize i am")
Guy: Because im your boyfriend and you love me... I'd really really be greatful...
I'm grossing myself out writing this sh!t! But this is probably going to end with her not doing it or doing it in an uninspired way...
Let's see a different more slick way:
Guy: Blah blah blah (mention back rubs randomly in the conversation then pause to think)... That reminds me of Amalia... She used to give the best backrubs (act like you're enjoying a backrub).... And she used to do it with such passion... like it was turning her on to rub my back... she wasn't much, but she was great at that...
Now it can go in many directions (including her getting mad that you're bringing up other women. But unless she's grabbing an AK-47 - who cares?) Just lead her from there to give you a backrub without asking for it... Jealousy is a hell of an influence... Just look at all the guys on here posting 20 paragraph stories about their girlfriend and other guys. That's very strong emotional investment... And that's what jealousy does...
Some commments on what you've written...

(I already had sex with this girl last week)
Good!
Now act like you've been there before.
Sexual said:
I kept the conversation light and casual and then added randomly: "send me some dirty photos... =D"
Try not to add randomly things like this... LEAD up to it... Much harder to do through text than through phone or in person! By asking for dirty photos - you are making her the prize. You are making the dirty photos the prize.... to be won!
Sexual said:
She says, "And convince me why I should send you dirty photos... And what kind you like ;-)"
Woman: "Convince me why i should" = her establishing herself as the prize... and you set her up for it perfectly...
Sexual said:
I end it with, "I like the nude kind and the you kind!"
You saying this = "Because you're the prize and i want to win you."
Sexual said:
I don't think that will cut it unless I'm more straightforward and I give her something to fantasize...
uhhh... what? She wants to fantasize about a man who does not dream all day of her naked photos. Women don't fantasize very often about what they already have.
Sexual said:
I'm adding, "Maybe a cute outfit and skirt with no panties on... a come get me pose... maybe halfway lifted shirt... now that's hot."
Get rid of the "Maybe" when telling a woman what to wear, etc.
This woman doesn't have much incentive to do this thing you're asking of her. There's so much wrong here.
Sexual said:
I bet some of you are masters of doing them yourself in person. I look down upon drunk photography, but I've only convinced really slutty girls to do a video. Any tips?
Lead up to it... If i want the sex to be more wild:
Me: (after having sex with a woman a few times; when talking about sex with past lovers) "Yeah, Krista was a wild one. She used to love when i called her a "s!ut" and "*****" in bed, and when i pulled her hair and slapped her face."
Woman: (jealousy setting in, challenge arising, claws out) "You never do any of that stuff with me."
Me: "I think you're too much of a good girl for that stuff...."
etc.
etc.
etc.
Understand that just because a woman complies with something - does not mean it was done correctly. Just like if she refuses to do something - that does not mean it was wrong.
