What's wrong with making love scenes? I'd advise Desmond to stop going to that church. They won't be able to provide the basic necessities of life for him and they want to ruin his career. He should concentrate on his career. I believe we serve an understanding God and he'll definitely understand that Desmond's only doing his job.
As for his wife, he should try and make her see reason. I think she's jealous and feeling a bit insecure.
