Why does my boyfriend still pull out?

We have been together for 4yrs. No we are not married, and neither of us wants to get married. I’ve had an IUD for 3 years and not a single pregnancy scare. He used to never pull out, but recently he has. Does he not like my body anymore? Do I not feel good? Is it something emotion wise? I’ve asked him about it, as he knows I love when he finishes in me, but he never gives me a straight answer. Any ideas?
