Mrs Bushell said the play showed how far society had come, in regards to how people used to behave and treat each other.
She described the play as a cross between The Young Ones and Fawlty Towers, in its style of humour, and said the title should give people the gist of what it's going to be like.
"It's hilarious, and it does contain mature themes."
Prostitutes and cross dressing, a policeman and feminist views were in the mix.
"We were looking for an end of year comedy, something nice and light so everyone could go off on their summer holidays in a good frame of mind.
"And I particularly wanted to do a New Zealand comedy because as Kiwis we relate to the humour."
Mrs Bushell said the show was fast paced and dealt with "just about every gender issue that's currently in our society in a really funny way".
"It takes a good look at how people don't listen to each other and how miscommunication happens - like when people hear something and get the wrong end of the stick."
The plot follows Matthew who has been elected sexual harassment officer at the university he studies at.
His best friend Anna is part of a feminist poetry group and they have forgotten to book a venue for their meeting.
Anna asks Matthew if the group can use his flat, which he agrees to.
But when his cousin arrives, "sleazy Brent from Palmy" who is only interested in three things - girls, sex and booze - Matthew has to handle the situation of the two opposing factions in his flat.
The seven cast members, a mix of experienced actors and new talent, have been rehearsing the show for eight weeks.
"I'm looking forward to seeing the whole thing come together and having the audience really realise how far we have come as a society."
The Sex Fiend runs from November 25 to December 5 at the Carterton Events Centre.
Tickets are $24 and are available from Carterton Event Centre and Eventfinder.
"If anybody is stressed at the end of the year and needs a laugh then this is the place to be," Mrs Bushell said.
