Ianto raised an eyebrow slightly at the idea that they would be learning anything about this sort of thing in the Academy of all places, that there would be any sort of formal education on sex, but then he supposed that well. Why not. It was in the future, it was good for everyone to know, and without the hangups of the 21-st century... Well. There wouldn't be any problem with it, he supposed. He smirked slightly at the idea of Sulu sitting through a class learning these sort of things, but he pushed that from his mind for that moment.

He threw an arm out in the direction of his bedside table, flushing slightly that it was so close at hand, that he had everything so close at hand in every room, but. Well. Ianto liked to be prepared, and with someone like Jack around, it was only practical. "Should be in there, somewhere," he said, with a bit of a smirk, amused that for the second time that day, he was sending Sulu digging through his drawers like this.
