Mandar Ponkshe (Gulshan Devaiah), is an atypical youth, a sex addict, and a player. In his early 30s, he is only interested in 'scoring' one night stands while his friends are all married with kids. The movie opens with one such scene where his friends tell him to get married as he is too old to screw around. In turn, Mandar explains his philosophy about sex as a purely physical act, somewhat akin to the satisfaction of the 'perfect' bowel movement. 'It's a physical need' he philosophizes, whereas love is a different ball game and isn't necessary for sex.
The narration now moves back several years to Mandar's early teenage years. The year is 1989, Mandar along with his cousin Dilip (nicknamed Yusuf as a tribute to the thespian) visits his village in Maharashtra where their cousin Kshitij is already waiting for them. 15-year-old Kshitij is studying in a military school and is mature beyond his years in his views and aspects about marriage, love, and sex. By the end of their vacation, Mandar realizes that he is no longer a kid. His life becomes more exotic as he starts to woo girls, watching adult films and fantasizing about ladies.
Later in the year 1995, Mandar is now grown up and is an engineering student in Pune. There also he is accompanied by his cousins Dilip and Kshitij; the latter is an army officer by now. Mandar stalks Parul (Veera Saxena) only for having sex with her. While making out in the hostel room, they are caught by the warden and Mandar gets expelled from the hostel, leading him to rent a small flat. There he meets a beautiful housewife Jyotsna (Sai Tamhankar) and sets his sights on her. The dapper Kshitij, in the meanwhile, beds a steady parade of stunning girls at Mandar's flat. In a side plot, one of Kshitij's many girlfriends has a friend Anju who is being sexually abused by her own father. Incensed on learning of this heinous act, Kshitij beats up the father and takes Anju and her kid brother away thus rescuing them. The ordinary-looking Anju has a maturity and strength that gradually makes Kshitij fall in love with her. In an amusing scene, Mandar and Dilip talk about how Kshitij didn't fall for any of the pretty girls he was seeing but fell in love with a dark-complexioned plain girl. They both conclude with a racist joke that love is not only blind but color blind! Kshitij marries Anju and they eventually have a son.
Getting back to Mandar's dalliance with Jyotsana, their casual flirting gradually reaches a point where they start an affair. Here is a marriage that has petered into nothingness, given her husband has let himself go out of shape and humor. Jyotsna needing sexual fulfillment finds it in Mandar. Their furtive affair carries on for a while, Jyotsana visiting Mandar's flat from time to time before Deepak finds out. Once again Mandar is forced to shift residences and finally ends up staying with Dilip. In 1996, Mandar meets Parul again in order to keep in touch with her and is left heartbroken when he finds her with another guy, Alok.
After college, Mandar is shown working a full-time job but is involved in a booty call arrangement with an older married woman who goes by Savita Bhabhi. After years of loveless one night stands, he takes Dilip's advise and decides to meet some girls through matrimonial sites. His strategy of being honest about his past affairs upsets most potential matches who are orthodox, conservative girls. When he finally meets Tripti (Radhika Apte), he is so smitten by her that he decides not be honest, but instead projects a holier-than-thou image. This almost backfires, as Tripti turns out to be a very open-minded girl who has no hang-ups about her own past and admits to having been in relationships before. Now stuck in a lie, Mandar has to continue projecting himself as an orthodox, colorless man. All the same, the two continue to meet and start liking each other.
In due course, Kshitij is killed in an encounter with insurgents in Kashmir. Mandar again is left heartbroken from losing his cousin and friend. This incident brings Tripti close to him as she comforts him. They eventually get engaged, but Mandar is having a tough time with the idea of monogamy. He has one last encounter with Savita Bhabhi. Worse still, while on an errand to pick up a distant relative from the airport, Mandar assumes that the person hasn't turned up and instead tries to pick up an attractive woman who turns out to be the distant relative. Embarrassed and ashamed, Mandar barely gets out of the situation by the skin of his teeth.
At this point, Tripti's ex-boyfriend Chaxx (Suraj Jagan) enters the equation. Cool, suave and charming, Chaxx is all that Mandar is not. That and Tripti's history with Chaxx trouble him no end and make him insecure to the point where he assumes that Tripti is leaving him for Chaxx. Mandar decides to confess the truth about his sex obsession to Tripti and does so. Tripti also reveals that she got pregnant when she was with Chaxx and there was nothing between them as they have broken up. Tripti makes it clear to Mandar that Chaxx abandoned her when she needed him the most and therefore she can never take him back. She also tells him that Mandar is her present and she wants a future with him.
The film concludes with Mandar very happy as he is getting married to the girl he loves as he narrates the mishaps between Tripti and himself to his cousin Dilip.
