Overreacting ?????

So after bein In a relationship for 4 years things kind of become a routine. Is it wrong of me to want my SO to flirt with me, give me hints, lead me on, to make me want to give him head/have sex. Like him randomly asking me... You feel like suckin my dick... Just doesn't do it for me, of course I don't if you ask me like its a chore. Even after we lay down if I try to hint at it, for example tonight I asked if he wanted to watch a movie when we went to bed which kinda translates into im gunna feel you up and initiate sex, like it used to, and he says nah I'm tired I don't really feel like it. So then I'm like damn I was Tryna get some, it's just nice if we flirt with each other and tease each other or slip into it like we're not 60 yrs old, and he just says he's tired cause he woke up early, but we can sleep all day tomorrow. I kinda got offended and he says "well sorry if I didn't jump at the opportunity", ....like something's wrong with me. Of course I take it to heart and get upset and just leave the room. Am I overreacting or should he be more sentimental ? I just wanna feel like we are still dating !!!! Cause after all were not married yet.
