Im mortified

so I was supposed to end my period yesterday, I woke up yesterday without blood and went the whole day without seeing any. my boyfriend came over and i had told him I was off it so things started getting all hot and heavy when he pulls down my pants and panties only to find that their covered in blood

I pull them back up horrified that he saw that, its my first period since we got together and I guess he’s not down for period sex. anyway I try to start things back up again and end up giving him a blowjob. Once he got home I texted him and apologized and told him how disgusted i am that he saw it and he said he touched it too. he isn’t making that big a deal out of it but for some reason i can’t get it out of my head that it’s scarred in his mind like it’s scarred in mine.
