Help please

Soo me and my boyfriend have a pretty active sex life i'd say.. usually 2-3 times a week (we both have high sex drives) I keep finding myself with a small issue, as in me always doing all of the work. He'll often ask me for a blowjob and i usually always do it, but i dont get much back in return. Any advice on how to ask him for foreplay and maybe him to go down on me, hes never done it to me and im getting so unnecessarily frustrated...
