My boyfriend only wants to have sex about once a week, if even, but I am used to us being intimate every day or every other day. I have already brought it up before but I do not know how to bring it up again without making it sound like I have been unhappy about his low sex drive recently. He tells me it is because it feels insecure lately and he's been so busy with work that when he is with me he just wants to relax. I don't know how to handle this because I don't want to keep bringing it up, and I feel that it is wrong of me to get angry when he doesn't initiate. What should I do?
