Opinions?

So I started this seasonal job that's like right next to my SO's house. I work graveyard shift EVERYDAY so I'm either working or sleeping most of the time so I dont spend much time with him. We went from having sex at least once a week or more to only having sex once in the past month. I feel way too tired to even think much of it. But then he commented that if he didn't start things nothing would ever happen... I consider myself a conservative person when it come to being intament and I usually feel awkward starting things cause he usually would tease me saying no to kisses or anything like that, which doesn't help me. I dont really know what to do... I feel like I should try something but when I think about my mind just goes blank.
