What should I do???

So my boyfriend is always asking to either have sex or for something and he always gets his 100% of the time but in the year we’ve been together I have NEVER once gotten mine. Like he will literally do something for me for maybe 2 minutes but then he’s ready for his and as soon as he finishes he’s “too tired” to do anything else for me. It’s gotten to the point where i don’t even want him to touch me but if i don’t do anything for him he gets mad and stop talking to me so then I feel like i have to so i can keep my relationship. I know i care about him but I’m tired of feeling used.
