I have not familiar with this television series, but such controversies over portrayal of intimacy have always risen in the past.
Intimacy physical and emotional is very much part of a deep rooted romantic relationship. Sometimes intimacy exists without such relationships too. We may debate further on moral constructions of such intimacy, but the fact remains intimacy is a part of life.
There is nothing wrong with showing intimacy in television or movies at all. Of course people will argue that intimacy is not absolutely necessary. The story can go on without intimacy. However, intimacy is part of the relationship; and when you choose to skip it, you are portraying things in full perspective. Of course it also depends on how it is portrayed. Some things are cheap and make you squirm, somethings are well done and aesthetic that you feel the romance, sensitivity, emotions and its not just physical.
The problem is that in desi culture physical intimacy is considered taboo. It is something that is to be hush hush. People may accept it in western shows and movies, but something desi has to be more pure. I would not call it a double standard exactly. Its a cultural aspect, people are very protective of their cultural portrayals and it will take some time for them to accept changes.
I do not think that intimacy on screen influences children. Kids nowadays are influenced by many factors. They pick a lot of things from friends. With the internet, many kids come across a lot of objectionable and really cheap stuff automatically online. Intimacy in popular shows and movies, should actually give parents an opportunity to talk about intimacy with their children. Parents should influence children and not television or other media. If people stopped shying away from intimacy, they would be better positioned to discuss it with their children, especially impressionable teens and guide them to a healthy attitude towards intimacy.
Btw I love how we are not bringing up words like sex, nudity and po*nography. đ
