Did Junito really penetrate Ricky?

There was an episode where Ricky was willing to prove to Junito that he cared for Junito by letting Junito have anal sex with him. It was the part where Ricky was in bed with a red bow covering his ass and nether regions because it was Junito's birthday. I was wondering, did Junito really penetrate Ricky or otherwise because Junito was HIV-Positive and with Anal sex being the #1 risk of catching the virus, Ricky probably has it or otherwise. I remember Junito telling Ricky that he didn't have to do it but Ricky went on ahead and says go ahead and then the scene ends there. The scene is on Logoonline.com under the clips section of Noah's Arc.
