definitely get checked out its always better to be safe than sorry. typically you would know but necessarily. I wish you luck and hope all is clear.
yeah please get tested for stds or for evidence of rape. If you suspect you have been raped also contact the police. Its totally possible and you're totally right for worrying. Please get help.
Oh, having sex with someone that is in a black out stage from drinking isn't consensual sex. It would be impossible for it to be as you aren't in sound mind at the time. Anyone that has sex with someone in this state is taking advantage. That is my opinion anyway.
To answer the posters question, I don't know if you'd notice having been raped or not. I think that being tested would be prudent. This is an old post and perhaps you have been by now.
I feel like there's also the small chance that it could have been mutual sex considering you blacked out....?
You would know and your underware would have been off.
