What the best way to please your man sexually?

I have been married for almost 7 years and I feel that my husband is getting bored in our sex life I mean I do talk to him but he always say it fine but I know deep down it’s not. My husband is a very sweet man I just want to be able to give him the head he wants but he seem like when I do suck him I be sucking his dick for a long time to the point my jaws hurt and I can tell it disappoint him because my husband loves head but that’s one of my weakest area and he only wants to have sex with me bending over or laying flat on stomach because that’s the fastest way he comes. I’m at point that I don’t know what to do we have a trip coming up next week I really want him to experience the best sex he ever had not to mention my husband had sex with over 60 something women before he even met me but he was the first guy I ever performed oral on and we have no kids but we are trying to have a baby. Please help me I really want him to have a great trip this for our anniversary and his birthday.
