He's just not that into sex???

I'm going crazy here. Just this past year with my bf we've had sex maybe 6-7 times give or take. He tells me stress kills his libido and I've been very supportive and patient with him. I love his to death but it kills me we have almost no sex life. I work nights and he works days so we are just on different time clocks and there are a lot of other factors.

What makes me feel bad is he doesn't wear his emotions on his sleeves like I do so it feel like he isn't bothered at all we don't have sex or anything. I don't even know how or if there is a way to turn him on. He either is in the mood or not and most times not. I hate to ask him cause it is awkward and really hurts his and my feelings/mood.

With Christmas coming up in took a chance and got a sexy Santa outfit for him. But honestly I'm having shoppers remorse because I'm afraid to try to surprise him and him not want to again. I know he doesn't mean to hurt me by saying no but obviously I don't take it well. I get so much fear, jealousy, and doubt stirring in my head because he isn't into sex like I am. I feel so alone and so so beyond frustrated. I love him and want him so much and all I want is for him to want me to.
