nudes?

tmrw i need to send my man a pic bc its his birthday and like i am on vacation and wont see him for a rly long time and idk what to send like not nudes but something that would turn him on with out actually seeing my boobs and butt bare naked so like what are some tips or advice you guys can give me, would just a mirror pic in my underwear be okay ? like what do you guys send to your man ?
