Intimacy disappointment?

I am going to be married to my fiancé (M29) in a few weeks and we've been preparing tirelessly while both working full time. We find one another incredibly attractive and sometimes he will initiate a stop for a break and we'd enjoy one another on the couch in between, for example, placing the flooring in our new house or planning the playlist. For example, after not too long of being together, if I am on him he will move me off of him and I'd move off expectantly and be somewhat surprised to see him buttoning up his shirt. I've been feeling really confused and, at times, disappointed that he only stays with me for less than ten minutes right when I am really feeling him. I feel a lump in my throat and an unpleasant throbbing in my chest for... longer than I'd like to admit almost every time. When he doesn't give us a moment he kisses me long and hard or grabs me when we are alone and I feel a rush that I usually don't get an outlet for.

I want to tell him to stop touching or kissing me like he has been unless he is going to give me thirty minutes, give or take. But I don't want to hurt his feelings or him to feel like he needs to check his watch when we are sitting together. He is looking to get the work done as soon as possible so we can get him fully moved in but it has been hard on me. I don't even know how to ask him. I need advice.
