I don’t make out with my bf

His breath usually stinks , probably because his teeth are over crowded. His lips are usually crusty to lol... I love him but when he tries to kiss me I get disgusted 🤷🏻‍♀️.. I’ve made out with other people bf / never had an issue but with him I just can’t lol the most I do is peck. I need advice has anyone dealt with something like this bf.
