Although ejaculation might be exciting in pornographic films, it is not something that everyone enjoys in real life. If you want to ejaculate, or if you want someone else to ejaculate, please consult first!

If someone merely watches pornographic films to learn about sex and relationships between the sexes, then they might think that in the final stage of most sexual acts, men will sit up, masturbate, and ejaculate on their partners. They might also believe that partners always enjoy this scene.

Since hardcore pornographic films (which show real sexual acts of people) came into existence, ejaculation has always been a major feature of such films. In pornographic films featuring the male genitalia, a clear depiction of ejaculation is crucial because it can "show" that the actor has reached climax (although ejaculation and sexual climax are different). However, withdrawal ejaculation was not invented by pornographic films.

However, you may already know that not everyone enjoys ejaculating on others, nor does everyone enjoy being ejaculated on. Some people (regardless of gender) consider this somewhat embarrassing, similar to spitting on others. Some people also prefer to feel their partner in their arms and kiss them during the climax, rather than watching them masturbate.

However, some people do like it. They like it because their partner really enjoys it, or because they are excited about doing some sexual things, or because they enjoy being humiliated (if they are role-playing in a relationship of mutual trust and respect), or simply because they like it. See the first comment below.

But I'm sure that the person you like will eventually get tired of it too. This seems to be the case in pornographic films. This is called a "profit-making scene", and the producers of pornographic films believe that this is what the audience wants to see.

So in real life, remember, what you do during sex is your own business. If you want to ejaculate on your partner, you should politely ask. If you don't want your partner to ejaculate on you, you can say: This is your body, and you have the right to refuse anything you want to do to it. Just like any matter related to sex, consent is key. You can only know whether the other person is willing by asking first.
