SO doesn't send sexy Pics/Sexts me?

Emma
We're in a long term relationship, and we're doing long distance right now. I've been meaning to send him cute and sexy pics (without my face of course) but I kept holding back cuz he never addresss them or sends me anything back! I sent him one yesterday cuz I felt really cute but he didn't mention it all! I've asked him before if he doesn't like them and told him it made me self conscious when he doesn't reply but he said that he did and that he doesn't delete them. He's sent me pics only once like a year or two back. I like sexting but if he doesn't reply to a pic idk what else to do? Or how else can I bring it up? I thought guys were supposed to be into this and he's not interested at all 😞
