My boyfriend said I smell down there..

My boyfriend and I have been together for over a year now. We are very sexually active, multiple times a day. However whenever I ask him to go down he refuses. He’s done it two time the last being back in November. We got in a huge fight last night and he told me that it’s because it smells down there. I’ve never been told this before and it doesn’t smell any different to me then it ever has before. I don’t know where to go from here. He gets whatever he wants sexually but won’t give me this one thing? 😩
