How to send nudes?

I was dating this guy for a long time and I we stopped speaking because I moved away for a while. I’m back now because I got a job in my home town and we rekindled. We’ve both been busy and haven’t seen each other for a while but he plans on staying at my flat when he gets back from a family function out of the city in a couple of days.

I want to get him excited for our night and send him some sexy pictures.

If I do how should I frame the message with it?

What should I say?
