It's a good thing we don't apply the adage "These things happen. They always have and they always will" to crime in general. Murder/ robbery/ arson, etc. have always happened after all, and probably always will. Whoever wrote that opinion needs to think his (or her) thoughts through a lot more thoroughly.
Nevertheless, the highlighted part of the opinion (garbled though it is, and confusing consent, contraception, and general musings about relationships in one hot mess) pertains to accidental or premature ejaculation that surprises the man.
This bloke has said he got carried away. In other words, he decided to carry on regardless of the OP's wishes. He had no reason to believe she had consented to sex if it meant he ejaculated inside her.
A woman doesn't have to have a reason (such as contraception or fear of sti) for not wanting sex without a condom or for wanting a man to withdraw before ejaculation, or for making consent conditional in any other way. It can simply be her preference, and if the man doesn't like the sound of her conditions he doesn't have to have sex, and she doesn't owe him sex.
The idea that men are powerless in the face of their sexual urges or in the heat of the moment is one that has too often excused sexual violation of women, and it is regrettable that this notion still has currency despite the fact that millions of men practice withdrawal successfully.
