Meanwhile, in a previous report from Digital Spy, Quinto opened up on his previous performance in the play Angels in America where it made him think about AIDS awareness and sexual freedom.

"Had I been born a few years earlier I would have been in the sweep of that epidemic, there's no question about it," the actor told "Attitude." "So maybe there's a proximity alert that goes off for me. I'm not trying to say that people shouldn't take PrEP, or that people shouldn't have sex, or that sex isn't amazing. It is. I'm just saying we should support each other and be responsible, whatever that means to you."

Quinto added that there's nothing wrong with enjoying sex as long as safety is involved for everyone.

"Have as much sex as you want, and any way you want to have it, as long as you're accountable to the person you're engaging with," he said. "I don't think, frankly, that's a controversial thing to say."
