Is it normal that on porno movies the male gets his penis sucked after ejaculation?

Whats the story with , in porn, one person makes the person with the penis ejaculate-sometimes through oral sex but sometimes not and then after the sperm is hither and thither the other participant/s place the penis in their mouth/s. Is this normal day to day behavior in this decade? Surely people with a penis don't want it touched directly after the act because it is super sensitive.
