my kids are with their dad tonight but are back tomorrow, maybe for their sake I need to speak to the police
I didn't know you had dc. OF COURSE you need to speak to the police and you MUST put the safety of your dc before your pride, or sense of shame as the case maybe.
Your story is one that the police will have heard many times and won't be at all judgemental about. Many women join one, or more, of the numerous hook-up sites that cater for lonely singletons and many don't fully realise what they may be letting themselves in for. In any event, you imagined that any sex that occurred would be wholly consensual but unfortunately it wasn't, with the result that you were sexually assaulted and left with bites, bruises and vaginal and/or anal bleeding.
If you don't want the police coming to your house tonight go to A&E and ask for your injuries to be recorded and reported to the police. Take whatever clothing you were wearing and bedding or other material that may have traces of his/your DNA with you.
As I'm sure you know, you'll need a number of tests to rule out diseases that can be transmitted by bites and penetrative sex and it's to be hoped that the "bleeding down there" will be resolved without surgical intervention.
As I've said, the police can be exceedingly discreet and there's no need for anyone to know outside of you and them. Be prepared for a long night and call in sick in the morning.
I'm sorry to say that you haven't only put yourself at risk. By allowing this man into your home, you've compromised the safety of your dc and you MUST report this assault to the police. You don't have a choice in this matter. It HAS to be done and, hopefully, this will give you the impetus to seek bereavement counselling as well as whatever is offered to you by specialist police officers who work in conjunction with Rape Crisis.
