Jay redeemed himself with The Price of Love (1995): he plays a gay hustler who shows the ropes to the "gay for pay" Bret (Peter Facinelli).
His dreaminess quotient decreased when he got a reputation as a hard partier. Even tearing off his shirt during a party at Fox didn't help. Kids like their teen idols wholesome and innocent.
During the late 1990s, Jay did a few buddy-bonding movies.
Blue Ridge Falls (1999), about four friends bonding over a murder. His Shane buddy-bonds with Danny (Peter Facinelli).
Hollywood Palms (2000), about the interconnected lives of residents in the Hollywood Palms apartment complex. Jay plays rocker Riley, who buddy bonds with Dexter (Jeff Russo). Together they try to prevent a murder.
But when he graduated to adult romantic leads, the buddy bonding dried up. All I could find was a 2005 episode of Medium: Jay plays Tommy Lehane, best buddy of the medium's brother Michael (Ryan Hurst), who might be a murderer.
More recently Jay has played Stan Rizzo, the homophobic art director at the 1960s ad agency on Mad Men (2010-2012), and the non-homophobic dad of a gay teen on The Real O'Neals (2016-)
He's still quite muscular, and not averse to stripping down to his underwear.
