nude help?!?

Hey there ladies! So, my person and I have been together three great months. But the holidays came around, we had to go back to our respective homes from school (we are both freshmen in college). We were talking and Making jokes/hitting on each other lol. (I said is that a light saber or are you just happy to see me, I don't know why he likes me sometimes) and he said he wishes he could see me. Theeen, we got to the topic of nudes. So my question is, how nude you take a "tasteful" sexy picture? I've bever sent in before, but I'm confident in my body and him. However I'm not sure I want to put my face in it. This is just on example on what I'm struggling with lol. Any help would be much appreciated.  I'm more confused about lighting and poses.
