Too much affection from 27M to me 27F all the time?

My Husband is male 27 years old and I am female 27 years old been together since we were 18. We have 2 kids together. My husband says his love language is physical touch and I know this sounds bad but I've felt smothered by it lately. Don't get me wrong I love a cuddle on the couch, hand holding, a kiss in passing-but that's not enough for him. He wants to makeout everytime we kiss-even in the kitchen while I'm cooking dinner doing other things etc. He is upset if I don't "kiss him goodnight" again that involves a full make out session. And today he started trying to dirty text me in the middle of my work day! I prefer sleeping on my stomach, but he requires our bodies to be like connected all night. I feel like I'm always hurting his feelings but...we are grown ups, with children. I don't mean to be a prude but I can't be dropping everything to make out and send you dirty texts. Is there a way to communicate this without making me out to be a grinch?

TLDR: I (27 F) feeling smothered and touched out by (27 M) constant need for physical touch
