Husband's low sex drive

It breaks my heart. A week and a half has gone by and he's not the least bit interested in having sex. I have asked and tried to initiate multiple times and he refuses. I asked if he is masturbating and he said no. I have been because I actually get sexually frustrated when we go this long. I asked last night, "don't you at least want to have sex" he said "I was fine without sex before we got married. It's not like I'll explode." It makes me feel ugly and unwanted. I ordered a testosterone test kit this morning. I don't know if that's the answer or not. But I'm just so sad. I want to be accepting of my husband's sex drive but it hurts because I want intimacy. And he apparently doesn't need me like I need him.
