The athlete elected to testify in person in a Sydney court on Monday as Jones fights 22 charges of indecent assault and sexual touching without consent related to six men.
The athlete was a young teenager when he first met the veteran broadcaster, who was "overwhelmingly complimentary".
Jones would often call him "beautiful man" and "champion" and greet him with a hug, the court was told.
"If someone hasn't told you, let me be the first person to tell you that you're special," the former Wallabies coach would regularly text him.
"At first it was flattering and then I got a little uncomfortable about it because it was not something even my parents say to me," the sportsman testified.
After complimenting Jones on his floral arrangement, the athlete soon received weekly shipments of flowers to his home.
When the athlete fell into financial difficulty, he said he tearfully went to the 2GB breakfast host, who set up a meeting with a bank that ultimately didn't improve the outcome.
Years later, he said he was at a sporting function when Jones allegedly kissed him on the side of his lips, near the corner of his mouth.
"I recall thinking, like, 'f*** what just happened? Why would someone do that?'" the sportsman recalled.
"It felt like a long walk back to the table. I sat down. I didn't speak about it."
He said he hadn't consented to the kiss, which lasted a second or two, leaving him shocked and embarrassed.
"I think I froze at that time," the athlete said.
"I was in disbelief ... there's no reason to suggest why in this public situation you'd kiss someone this way."
Later that night, he recalled receiving a message from Jones with words to the effect of "I would like to be kissing you all night".
Jones acted on that impulse years later when the two were at his Circular Quay apartment, the athlete told the court.
He said the broadcaster kissed a path from his cheek to his mouth, saying things such as "I love you so much, you don't know how much I love you".
The sportsman felt the older man's genitals pressing against him and pushed him away.
"OK mate," the sportsman responded "defiantly" - in a tone to convey "get away from me," the court was told.
The man then left the apartment, he told the court.
When asked if he had consented to the kiss or the press of Jones's genitals, the athlete was adamant.
"In no way whatsoever," he retorted.
"I did not want to be kissed by him in that way."
He told the court he later confided in friends about the alleged indecent assault and sexual touching incidents.
The third complainant in the months-long trial, the sportsman is the first to elect to give evidence in person, rather than from a remote room.
Jones claims the alleged incidents never occurred and his lawyer previously argued money, desperation and opportunism were at the heart of the case against him.
The veteran broadcaster has pleaded not guilty to 20 indecent assault charges and two more of sexual touching, related to six men.
The alleged incidents span from 2003 to 2020 - the latter half of Jones's long-running, highly successful broadcasting career
The court is in a closed session for the athlete's testimony.
Media have been permitted to dial in from a remote room.
