Wichita ? Two women testified at a military hearing Tuesday that they would not have had sex with an airman had they known he was HIV positive, and one said she believed him when he said he wasn’t because he was in the Air Force.

He has been charged with violating military law by having unprotected sex with at least 11 people without telling them he was infected.

The two women who testified Tuesday detailed numerous encounters where they had unprotected sex with the airman, including at several so-called swinger parties in the Wichita area. Some of their sexual encounters were videotaped by the 43-year-old airman’s wife, they said.

One woman, from Topeka, testified she asked him whether he had any sexually transmitted diseases and believed him when he assured her he didn’t.

Asked why she believed him, she tearfully replied: “Because he is Air Force. They have integrity. I trusted him.”

The woman testified about numerous sexual encounters between May and June of last year. Asked on cross examination whether she had been infected with HIV, she said no.

The other woman, who now lives in Bailey, Colo., also said on the stand that she would not have had sex with the airman at swinger events had she known he was HIV positive. She was not asked whether she had been infected.

The airman, who was stationed at McConnell Air Force Base with the 22nd Maintenance Operations Squadron, has been under arrest there since Aug. 9.

Along with one count of aggravated assault for each sexual partner, he has been charged with violating his squadron commander’s October 2009 order to notify his sexual partners about his HIV status before having sexual relations and to use a condom. He also has been charged with indecent acts for allegedly having sexual relations in front of others, adultery and obstruction of justice.

Tuesday’s Article 32 hearing, similar to a civilian grand jury, is used to determine whether there is enough evidence to proceed to a court martial proceeding. No plea is entered at this stage.
