Reid sat on the edge of his desk---he preferred to keep it clean, or at least halfway so, so that he could sit on it when he liked. It made sense. Having one eye would certainly be a problem regarding depth perception, and it would make creating sculptures all the more difficult. Perhaps he would give Terry a break regarding anything three-dimensional, unless Darren could help him get over that and make it easier.

He couldn't help but blink as if someone had thrown something at him at Terry's straight-to-the-point question, however. It was so random in that moment that it had thrown him completely off guard, but he recovered quickly and erased the dumbfounded expression off his face. "Erm... Yes, I have." He said after a moment. It felt odd to speak of this with a student he taught, though others had come to him with sex questions more than once in the past. Nothing quite so personal to him, however. "I find it a... thing that's best shared with a specific person, because it can... lead to dependence..." He pursed his lips, turning his own gaze down for once. That was all too true for him. But then, his age had been a large factor. He looked back up. "Why do you have such a specific question...?" There had to be something fueling it, after all.
