<human>: So my boyfriend and I are still virgins. We ocassionally indulge in foreplay which includes fingering, etc. We don't get to do it often because we live on the university campus, and the campus has very strict rules about men and women mixing. So when we do spend time alone, we are basically pretty desperate for each other and there is no question of asking for consent before getting it on. 

But the other day, we got to be alone for about half an hour. I was really tired, had an exam the next day, and was also on my period. I was really, REALLY not in the mood to go beyond kissing and cuddling. He was really turned on and quite drunk as well. When he tried to finger me, I said no multiple times and even pushed his hand away. He decided to do it anyway. I stopped him after a couple of minutes by FORCEFULLY pushing his hand away, because it really started to hurt. 

I feel horrible now, and violated in a weird way (even though on another day I would have been completely fine with it).  We've also been having small disagreements about other things lately, so I don't want to seem like I have a problem with everything he does.  Should I let him know about it? I know he will feel awful if he does know. Men of Reddit, would you want your girlfriend to tell you if they felt violated during just one incident, or just not let you know and just be more assertive the next time so that the signal is clearer?

Can you summarize the given text in a few sentences?
<bot>: My boyfriend fingered me though I was completely not in the mood for it. I would have been okay with it had it been another day. Should I let him know that I feel violated?
