Help! How often should I send nudes?

So this is the first time I've been in a text relationship with a guy! I've sent him nudes and he sends stuff back... Thing is I have like 50 pics of his dick in all different angles

hahah... I've sent him like 3 pics of my tits! I just feel weird sending basically the same picture of my boobs all the time. How do you girls do it? I'm so confused...

Do I just send him shit everyday.. Do I dress up? Like a bra all the time? Help. I have no idea how this works! Give me ideas! BTW I'm 23!

*whispers* help...
