Step son went to the hospital

Okay guys... So this is my 3rd update today. Basically my step son just got back from El Salvador. He visits his mom there. I found a walmart back of his boxer briefs and they all have so much blood on them. It was like a period. He's 14 and I sat him down to.ask about it and he just shrugged and wouldn't tell me anything. I called my husband who wasn't supposed to be back until Sunday for work related stuff..I told him and he's pm his way back home. He's in a different state. I talked to my step.some saying we.need.to.go.to.the hospital to make sure he's okay. He kept saying not but I told him we have to. After an hour of arguing he sighed and said okay. At the hospital they had me step out. What I was told by the doctor he said the blood was coming from his rectum and just by looking he can tell their was a sexual assault. We needed my step some consent for a rape kit but he said no and wouldn't budge on it this time. The doctor did tell me he will have to report this to cps because he's a mandated reporter. My step so won't talk to me about what happen, I tried having him talk to his dad on the phone and he still refuses to say anything. My husband is on his way back and I'm hoping seeing him in person will help him open up.

Edit: Destiny if you don't like my post than move on. You have no idea who I am or who he is nor anyway of finding out.

I'm not the only one on here who's made a post about their child or step child's trauma. One women with a 17 year old step son has made.posts about him constantly and all she gets is praise. Why am I getting hate. Literally all.that women gets is "You're such a great step mom!"

@Yetti how I found his underwear was in the laundry room I went into the closet to find fabric softer and I found a Wal-Mart bag hidden under stuff and opened. I was like snooping in his room or anything.
