Sexually Frustrated 😩

We are currently in a LDR due to him having to move to another state with his family and whenever we are on Skype we sometimes mess around but lately he just keeps playing guitar. Whenever he's in a mood I'll drop everything and we'll have a good time but I feel like when the situation is reversed I have to go at it by myself. I've dropped hints that I'm in the mood but he ignores it completely and it's so frustrating! Advice would be much appreciated!
