My friend cannot have sex. Could this have to do with her body rejecting intercourse?

She is a 20 yr old girl that has been molested and raped in the past. Just recently she and her ex tried to have sex, but for some reason something inside of her kept him out, yet he was able to finger her, and a doctor was able to give her an exam. She doesn't have a hymen, but , well this is what she said....

"her: me and him tried but...
ok, he has fingered me, obviously, and most the time he couldn't feel anything blocking the way, but every once in a while he could.
When we tried having sex, it was like there was something blocking the way, but i no longer have my hymen."

Me: hmmm..might be the muscles....have you thought about going to a doctor and asking?
Her: no money
i went and got checked out
and he got straight to the cervix
i was crying and freaking out lol
but he got there
twice
with no issue"

Thats pretty much it, if someone can give me some information on this or some help, it would be greatly appreciated.
