My husbands penis is suddenly grossing me out.

I enjoy giving my spouse blowjobs a lot. He’s a very clean man, and his penis is always clean, and never smelly or anything like that.

Anyways. I was giving him a blowjob the other night and the natural smell of it started grossing me out (this is how it always has smelled and never bothered me before). I was barely able to give the blowjob over how much it was grossing me out. Even now while typing this out and thinking about the smell and taste of his penis is disgusting me. It didn’t smell or taste any different and it’s never bothered me before but it grossed me out a LOT out of nowhere. Has this happened to anyone else? Does anyone know what would cause this sudden disgust?

Edited update: I am not pregnant
