Nudes

Okay so I’m in a long distance relationship, I talk to my bf everyday on FaceTime and we see each other often, but I feel like I’m lacking attention is a sexual manner I guess, I know hes attracted to me like that, but I sorta want to send him nudes like I feel like, it would be a good way to connect us in that way being apart, but idk how going about telling him I want that. Any advice?
