A Roman Catholic priest known for his charismatic style has compared gay sex to cramming a bagel in your ear.

According to the Detroit Free Press, the Rev. John Riccardo of Our Lady of Good Counsel Parish in Plymouth, Michigan described his analogy Wednesday during a three-day national conference titled Welcoming and Accompanying Our Brothers and Sisters with Same-Sex Attraction.

Despite its title, the conference, which drew about 400 participants, struck an unwelcoming tone, claiming gay sex is harmful and urging LGBT parishioners to remain celibate.

Riccardo described how he explains to teenagers the sinfulness of gay sex without being too explicit.

“This is the question which is asked by junior-high kids: Why does God hate gays?” he rhetorically asked.

“Here's the image that I use,” he said.

“[What if] I just rip open a bagel, I take it, and I cram it in my ear. What would you say?”

The teens usually respond by saying that the bagel “doesn't go there.”

“I say, 'Exactly.' That will ruin your ear canal,” Riccardo said.

Another speaker, Dr. Timothy Flanigan, lectured on the risks of gay sex, saying that “anal sex is risky, dangerous … And oral sex also carries with it its own risks as well,” seemingly unaware that such acts are also carried out by opposite-sex couples.
