Ivan Sergei in 'The Opposite of Sex'

 Ivan Sergei (/ˈiːvɑːn/; born May 7, 1971) is an American actor known for his work in television.

 The Opposite of Sex is a 1998 film written and directed by Don Roos and stars Christina Ricci, Martin Donovan and Lisa Kudrow.

 Ivan Sergei as Matt Mateo

 Teenager Dedee Truitt (Ricci) runs away from home after her stepfather's funeral and moves in with her half-brother Bill (Donovan), a gay teacher in a conservative, suburban community in Saint Joseph County, Indiana.

 Dedee seduces Bill's young lover, Matt (Sergei), then tricks him into believing he has impregnated her. In fact, the father of her child is her ex-boyfriend Randy Cates (Scott). She and Matt elope, leaving Bill and the uptight Lucia (Kudrow), the sister of Bill's deceased partner Tom, to track them down and sort out the mess. In the meantime, Matt's "bit on the side", Jason Bock (Galecki), attempts to blackmail Bill in order to track down Matt, claiming Bill sexually assaulted him while he was a student. Bill and Lucia find Dedee and Matt, only to discover Dedee has stolen Tom's ashes and is holding them for ransom. Randy also finds Dedee; they inform Matt that they are taking the ashes and moving to have the baby elsewhere. They escape but soon get into an argument that leads to Dedee accidentally shooting Randy. She and Matt escape to Canada, and Bill eventually finds them.

 Narrating the ending, Dedee sarcastically concludes that sex is precisely the opposite of what people should want, leading as it does to kids, disease or, worst of all, relationships. At the end of the film, the vignettes of the various caring relationships among the characters show the opposite of superficial sexual gratification.
