Boring sex

So me and my fiancé use to have AMAZING sex when we first met. we’ve been together for 2 years and had a baby 4 months ago. Over time our sex life became really vanilla and now its basically non existent. When we do have sex it’s just long enough for him to finish and then we’re done. He doesn’t seem to care about fore play anymore and I only cum when i ask him if he has enough energy to break out the vibrator. I’m so bored and frustrated with our sex life and even before the pregnancy and the baby it started going south. I’ve tried nicely mentioning it before and telling him what I like and don’t like and he’ll say he gets it but the next time we have sex it’s the same old thing. No foreplay, no kissing or touching just straight to the point and done. I don’t want to be shallow and have this affect our relationship but sex is an important part of a healthy relationship for me and I’m just not satisfied. Outside of sex were pretty happy but I feel more like a friend than a fiance to him. I love him to death but we don’t kiss or cuddle or touch each other anymore and idk what happened. Advice?
