What would you think if you woke up this way?

So this morning I wake up the the bed shaking. I live in Wisconsin so i knew it wasn't an earth quake. I then realized that my boyfriend was masturbating right next to me! I couldn't believe it! I was so grossed out, i know it is natural but shouldn't he have done this on his own time instead of waking me up from it?? I am bothed by this maybe more than i should be. I am over reacting?
