My boyfriend and I have been together for a year and a half, and we recently moved in together. We have a great relationship until it comes to sex.

I have a much higher libido than he does. TBH, I would be down for sex every night of the week, and he just isn't. I'm lucky if we're intimate once a week, and it's usually a result of me coming onto him. He rarely initiates anything sexual.

He says that during the week he is just tired from working all day, which I understand because we both work long hours during the week.

This has been a problem since the beginning of our relationship. I've tried to ask him what we as a couple can do to try to fix this problem, but he just shuts down and says it's his problem not mine. He made the comment last night that I "can always use my vibrator if I want it that bad." I don't want this to be the wedge in our relationship, I just don't know what to do.
