Is it true that they have fake dicks and fake ejaculation in porno movies?

i was on the internet and i always see those sites with people with 18 to 24 inches of penis. then i looked at it and i noticed that they were always holding it. then i heard on the internet that they use a device that goes under the penis to make ejaculation look like the real thing. is any of this true?
Answer:
No such thing as a 18+ inch penis. The men in the movies are normal sized men and as far as the ejaculation is concerned, the movie is edited with water and a powdered sugar mixture.
Editing works wonders in films.

Hmmm i dont no..maybe but it seems kind of far fetched i think that it woud be to much work to consturct a fake penis attach some device that shoots out giz while having it all hidden and attached with no seams.
