I think somehow Indian TV, the budgets they have and how it is shot, a liplock does not even look good. I have seen in a few shows where there has been a liplock and frankly it looks super tacky. Actually even a lot of Hindi movies the kissing looks awkward (like SRK and Katrina in JTHJ). I am going to conclude that Indians are not really that great a kissers 😆
I think we can't exactly compare cinema and TV. There is a greater intimacy between an audience and the movie - a darkened hall and you invest a few hours. On the other hand, a daily soap is more about familiarity. They are people who become part of your lives and I guess you don't want to see them kiss or get intimate. It is just a little too much information, I am unsure if I am clear.
Also, tons of actors are generally speaking uncomfortable with kissing onscreen. A lot of Bollywood A-listers don't. I think SRK did a liplock after doing some 100 movies. Probably did it because it was a YRF product.
Another thing I notice, the women actors are judged too harshly if they do kiss onscreen or wear a bikini, for example. I still remember there was some backlash when Aishwarya Rai kissed Hrithik in Dhoom 3 and after a few weeks they edited out the kiss even. So, yeah a lot of factors - culture, patriarchy, the works!
