Long Distance Love

My husband is deployed and he has been in Afghanistan for almost 6 months and we are having sexual issues. I want to meet his needs but some of the things that he has mentioned, I am not sure if they are outside of the will of God?? I just want to know what to do. I want to meet his needs but not do anything to get in the way of my salvation and my walk with God. But I know that me being a wife and being sexual is a part of what it is to be a wife to my wonderful husband. He is being very supportive and understanding in this matter, I just have no idea what to do with his request.
