Sexual hypnosis with straights?

A friend of mine (heterosexual) told talked to a male hypnotist who hypnotized him. After a while he started moaning and he got a hard on. When he woke up he started fantasizing about sucking his dick. It lasted for a couple of days.

Can that actually happen with hypnosis? Can a male hypnotist make me aroused even though I'm straight?

And if anyone wants to talk please send a DM.
