Is it normal that my roommate gave me a blowjob?

Yesterday morning, I woke up feeling EXTREMELY horny. I really wanted to relieve my throbbing sensation, but I knew it would be awkward with my roommate present. He only sleeps about two feet away from me. Luckily it was relatively early in the morning and I figured I had maybe a half hour or so before he woke up. I tried my best not to think about masturbating, but I broke after about five minutes. I slowly reached my right hand down my legs as my left hand elevated the blanket enough so that it wouldn't bob up and down as I stroked my dick. I began caressing my balls and slowly rubbing on my cock. I was as stiff as a rock. Feeling pre-cum gently slide down my shaft, I began to use it as lubricant as I massaged my dick. After about ten minutes, I really picked up the pace, pumping my clenched fist up and down. Just moments before climaxing, I let out a few subtle grunts that stirred my roommate. I did not, however, notice his slight shifting and figured I was in the clear to remove the blanket and reveal my penis for just a few seconds to cum. When I had abolished the covers, it only took a couple seconds for me to ejaculate, and boy was it spectacular! Semen flew into the air majestically like fireworks on the Fourth of July. After discharging what felt like a cup of my liquid seed, I let out a big sigh of relief. With my eyes glazed over and mouth smiling, I turned to my right and saw my roommate with his eyes wider than I had ever seen them. In half a second, I pulled the blanket back over me, but it was obviously too late. He had witnessed the final seconds of my extraordinary masturbation session. Immediately I apologized for what he had seen and assured him that I don't usually do that. He didn't react. Initially, I thought he was mortified at my act due to our close quarters, but then he said something. "I'm not mad, dude. That was incredible." Stunned, I replied, "Incredible? What?" He smiled and told me to relax. Then, he stood up, tugged my blanket covers off of me and declared, "Let's make that happen again." I was shocked and couldn't respond. He swiftly descended his head towards my genitals and licked up all of my cum. Before long, his mouth was enveloping my cock; his tongue swirling around it like a tornado. I had never received such an amazing tingle that resonated throughout my whole body. As he carefully washed my balls with his saliva and nibbled on the head of my penis with his neatly aligned teeth, I could barely contain myself. Once again, I shot out a huge load of my reproductive goo, but this time, in my roommate's mouth. Is this normal?
