crush asking me for dirty pics ._.?

[♥Gawjuss_$atanist♥]

The first time i spoke to him (November) up until now he's been the nicest guy i've ever known. he appears to respect women and treat them right.. he doesn't swear or do drugs or anything like that. he's actually really into poetry and he's a really classy guy.. but i'm guessing he saw one of my "revealing" pictures on my facebook page, well.. it's not that revealing, it only shows a little, barely anything. anyways and then he told me he was sexually attracted to me and i was happy and everything, but then he asked that in time, if i would show him anything.. he did tell me that i can stop him if things get too awkward, but part of me still loves him and wants to please him (i'm actually kinda enjoying the sexts he's sending me) but on the other hand it doesn't sound like him at all. but i guess the fact that he showed me that side of him means he must trust me at least a little, right?..
i don't know what to do .-.
*shivers*
advice? D:
