Overly affectionate

I grew up in an affectionate-free household. Hugs and kisses were rare and I love yous were non-existent. With that being said, I do enjoy those things, in moderation. My husband on the other hand wants them non-stop. He will tell me he loves me 100 times a day, blow kisses to me constantly across the room, and I can't cross his path without being groped. Sometimes I do enjoy these things, but when I don't, I let him know that I need some space and he gets very offended and continues to do them anyway. I start to feel smothered and resist being touched all together. It makes me feel trapped. I feel there can be a "middle of the road" for this somewhere....Any advice?
