Haley Kalil Exercised 'Sexual Sovereignty' by Discussing Ex's Size, Lawyer Claims

12:24PM PT -- "Haley Kalil disclosed private and intimate details about Matt Kalil that were of no legitimate public concern and subjected Matt Kalil and his family to widespread ridicule and unwanted attention,” Matt Kalil's attorney, Ryan Saba, tells us.

“Haley Kalil shared these sensitive personal details about her ex-husband in an apparent quest to seek fortune and fame. Her actions were extreme, outrageous, beyond all possible bounds of decency, and have caused substantial harm to Matt Kalil, his family, and his business.”

Haley Kalil's well within her rights to talk about the Coke cans her ex Matt Kalil's packing in his pants, her lawyer says ... because she has erotic autonomy.

Matthew Bialick -- Haley's lawyer -- tells TMZ ... he plans to file a motion to dismiss Matt's lawsuit within three weeks of being formally served the summons or complaint, which hasn't happened yet.

Bialick says it's totally unreasonable to file a lawsuit on the basis of making someone liable for "exercising her sexual sovereignty by truthfully describing a sexual experience that left her in tears" ... adding it violates his client's right to free speech.

We're told this is just a taste of the argument Bialick will be making in the upcoming dismissal motion ... and we'll keep our eyes peeled for that penis-permeated petition.

ICYMI ... Haley revealed on a podcast her marriage to Matt was marred by his massive member -- which she described as two, maybe three stacked Coca-Cola cans.

Matt then filed his lawsuit ... claiming Haley's suit attracted "unwanted attention and invasive commentary from the public" while his family had "been forced to endure the ongoing public circulation of these degrading and deeply personal statements."

Matt also accused Haley of growing her follower base with the comments ... thereby unjustly enriching herself -- while his current wife became the subject of "increasingly frequent, disturbing, and alarming" messages.
