My bf woke me up by putting his dick in my mouth?

I take meds to be able to sleep. I went to sleep and I woke up to him trying to put his dick in my mouth. When he saw I was awake, he turned me on my belly and just put it in without any question even though I asked what the fuck he was doing. I was crying the whole time but he couldn't see it. I can't stop thinking about it. I feel so dirty and violated. We've been together for 4 years and we have a 4 months old boy.
