Lack of intimacy

If you told your husband or partner that you are bothered by the lack of intimacy in your relationship (I.e. kissing, having sex, cuddling) literally everything romantic and they told you they would work on it but never do what would you do? I’ve said this countless times to my husband and he always comes up with an excuse as to why he can’t show me affection or attention. The latest one is that he has just now started having a problem with kissing me unless both of us have throughly brushed and flossed our teeth. He says he doesn’t want my germs in his mouth 😂 yet I’ll go down on him and kiss him right after no big deal. I’m so tired of always asking for kisses or hugs or sex. If I were to completely ignore it by not initiating anything it would be like living with a roommate not a husband.
