Deployment intimacy (or lack thereof)

Forgive me if I sound new to this; I am lol. This is his first deployment since we got married, he’s on a ship. I’ve thought about sending him sexy pics, but I haven’t and he hasn’t asked for them. I mean, I’ve made jokes about doing it and he said that he’s never gonna say no to it but he’s never like applied Any pressure about it if that makes sense. Part of the reason why I haven’t sent any yet is because I kind of feel weird about it because what’s the point? He has virtually no privacy and he’s so buys, so I just envision him looking at the pictures and going “nice” then putting his phone away LMAO. So I guess my question is what’s normal??
