You have a point but I don't completely agree...they approach physical intimacy differently...also cuz one is a guy and one's a girl😆...and their current respective partners respond differently too.
Waise one thing I noticed...Jaise Uttu pinned her arms...Manik has never managed to pin Nandu's arms that forcefully...could also be cuz of the height difference problems😆...Uttu-Kriss are more equal in height.
Parth toh kinda just generally aligns her arms behind her back and it doesn't even look he's forcefully pinning them😆
