What thing a person uses to stop his ejaculation?

Normally when a person does sexual intercourse with a woman, he orgasms within minutes. But when we watch porn sex videos, it does not happen. What do they use to resist their ejaculation?

Porn videos are not real. They can stop and redo a scene if needed and sometimes they use fake penises and simulate ejaculation. I really recommend watching "The girl next door". It's a documentary film about the porn industry and what it's really like to be a porn star. Here is a link describing the movie:

A few minutes...normally?? What?? It's all about self-control.
