You are not a bad parent! Just depends on what you can take and what you can't lol.
We do allow mouth kisses in my house.
I've grown up with dogs. It's really no big deal for me. Maddie is disgusting, and sticks her tounge in your mouth. It grosses me out, but there's no way I can possibly keep her from doing it. If I pull her off of me, she turns her head sideways and licks the air.
Tucker doesn't really lick mouths much, but he gives "kiss" on mouth by like pecking your lips. it's adorable.
Rusty, the lab, is also allowed to lick my face. he's not disgusting, and he only does one or two kisses before moving to some other part of my body, like my arm. or my hand. or my foot.
