LDR with a Muslim

My husband and I are in a long distance relationship, hopefully not for long. In the meantime, how can we be intimate while remaining respectful of the boundaries in Islam regarding private parts. We can not see each other's private parts and masturbation is unclear. He is Muslim; I am Christian. I am still learning about Islam so I'm not clear on all the do's and dont's. Religion is not a barrier I just need to become more knowledgeable so I know how to connect. We do sexting, raunchy video chats with lingerie, kinky pictures but it's mostly me exposing myself. I want to enjoy my husband's body as well. Can I get some guidance that's considerate of Islamic practices?
