No idea. You cannot know nor can we, as your recollection is incomplete.
Remember, for rape:
(a) you must not have consented; here it seems you grunted, might have replied affirmatively or non-verbally consented.
(b) he must have lacked reasonable belief you consented; here we don't know what he might have thought, as we only have hazy internal monologue.
I would posit that you had an unfortunate sexual encounter, where things were lost in translation, and you should move on. It seems a leap to assume this man intentionally had sex with you when he knew you did not consent, even though he had the constitution to stop when you started crying. Probably try to control your level of drunkenness in future.
