Both movies are romantic comedies with a focus on sensual/sexual topics that are most often not openly taked about. "Love and Leashes" deals with BDSM and the romance plays a subordinate role (pun intended), while "My P.S. Partner" is all about phone sex, satisfying a persons needs and cheating in a romantic relationship. Both are quite funny and surprisingly sexy.

Both movies delve into the world of BDSM and how it may free the people involved. "Love and leashes" gives more of an introduction into the matter for someone with no prior knowledge but "Nana and Kaoru" as well shows one experienced partner and one newbie who discovers this new world. Both movies are ultimately comedies and have a slither of romance in them even though that is not the main focus.
