Not having sex for another 7 months

So my husband tells me that it "tastes weird" down there ever since I got pregnant (eight weeks currently). He hasn't gone down there ever since he told me he "couldn't do it anymore". I'm very hygienic so it's not like it's a nasty taste. And he's told me about his ex girlfriends being super nasty tasting but he still went down on them anyways. So that must mean it's pretty bad. I've done the "finger taste" and it doesn't smell or taste different to me. But he still expects me to go down on him after sex. I'm just thinking I shouldn't have sex with him until everything is back to normal. I'm sick of being told that everything is wrong with me (including apparently getting fat when I only weigh 122 and I'm 5 5"). To a person like me who has NEVER orgasmed, having someone go down on me a few times a month keeps me interested. And fingering never really does much. So if I can't have fun there's no point.
