You choose to read the wording “go past a human cervix” as true when it enters the pocket besides the cervix. All questions has been whether the boar dick can penetrate the opening in her cervix and enter her womb.
Simple physics disprove your description - that the boars penis turns around besides her cervix and then halfway down her vagina turns around and then forces through her cervix.
Try to take a tube and bend it, then it is not possible to elicit any force of the tip.
The last sentence is correct that if something is forced inside her will give extreme pain and bleeding too. Unless the woman is firmly tied, she will move so he don’t to it.
A last remark - the inside of the womb is sterile, and quit delicate, so anything that ‘scratches’ will produce bleeding and a risk of infection too.
