Was I unreasonable?

So last night I got in a fight with my bf. We had really good, intense sex but as soon as he finished me off he immediately got up, put on his boxers and said "oh, and get me a glass of water?" Then just laid down and basically started to fall asleep.

I thought that was fucking rude and I said the proper way to end a sex session is with a hug and a kiss, not treating me like I'm your maid. Idk. It really hurt my feelings. He just told me I was being crazy and irrational and rolled over and fell asleep. This isn't really normal behavior for him- he has his insensitive moments like men do but he's not usually such a dick. He kept going "if you don't want to bring me water, you don't have to, jeez. You will get mad over anything" Like that was somehow the issue. Like he just didn't get it at all. 

I don't expect him to cuddle me for hours but would it kill him to like not immediately rush to put his clothes on and stay in the bed with me for like 5 minutes? The sex was awesome and this fucking ruined it. Is there anything I should do/say? Or do I leave it alone. He doesn't react well when I tell him stuff bothers me.
