Naughty pictures

Ok guys and gals...I've been dating this guy for over 6 months now. And our chemistry is off the charts good! He's made me feel so good emotionally, physically and sexually. I feel comfortable enough to send him naughty pics and vice Versa. I was previously married and my ex never made me feel this comfortable so I never sent any sext or pics to him. I'm new to this but it's so exiting and very adventurous to me. Now let me say I do always protect my identity by not showing my face on some of these naughty pics. But I've ran out of ideas on how to take pics on my own and have them being classy yet naughty. Anyone have any tips? 
Guys what pictures do your SO's send you that drives you wild?
