Is it normal that my boyfriend reacted this way?

I've been with my boyfriend for a year now & we've been living together since August. We have a great relationship but I'm still learning learning how to accept the good & and the bad. The hardest to accept is his selfish behavior that appears a little more often than I would like it to. I don't know if this particular incident falls into the category of being selfish, which is why I need advice. 

I've been sick for the past week. The 2 biggest symptoms: my throat & ear are in alot of pain. Even though my boyfriend knew this, he still kissed me and cuddled with me, even though I warned him not to (almost as if he didn't believe how badly I was feeling). 

When I went to the doctor yesterday she told me that I had a viral infection. When asked if it was contagious she said: "cover your mouth & nose when you cough or sneeze, & you should be fine." For people who don't know, a COLD is a viral infection, the gravity & length of the cold depends on how strong your immune system is. You can't take antibiotics for a cold or virus, it has to run its course. According to the doctor, it could last up to 5 weeks. 

When I explained this to my bf, he freaked out! He wouldn't let me near him, no hug, no kiss (which I completely understand). But then he yelled at me when I accidentally mixed my salad that I had taken a bite out of with his, I had to beg him to show me any kind affection to show he cared (like a back rub), & since sex was "out of the question " he watched porn on his desktop and jerked off in front of me, as I was trying to fall asleep, but couldnt because I was in excruciating pain due to side effects from the meds.  He could have taken my laptop or his phone into the bathroom or living room.

When I woke up in the middle of the night, he was sleeping on the opposite side of the bed (his head by my feet). I've never had a boyfriend act like that. Knowing him, if we had a spare bedroom or a more comfortable couch, he would've slept in the other room.

What if my cold lasts another week, or more? It makes me feel like he's more concerned about himself then he is about me being sick.

My opinion, if you're in a commited relationship and you live together, and your partner has a cold, there's really nothing you can do about it, other than taking care of yourself. Take precaution by drinking plenty of water, take lots of vitamin c, eat healthy & workout to build your immune system; not by making them feel like they have a disease. It's only a cold!!

He has psoriasis, how would he feel if he broke out and I refused to touch him or sleep near him? He'd feel horrible. I know psoriasis is not contagious but it's still pretty nasty looking.
Believe me when I say that I would NEVER make him feel uncomfortable about it. 

Am I the one who's selfish, is his reaction/behavior normal?
