Otabek seems very tactile, likes both touching and being touched, arches into the hands on his chest. He makes another soft noise into the kiss, the noise feathering at the end when he realizes how sweet the whole thing is. Everything keeps being the best kind of suckerpunch, until he barely knows what way is up anymore, just knows what directions is Yuri, keeps pulling himself that way.

It takes him a minute to reorient himself again, when Yuri pulls back, asks the question. There's no hesitation, though, already reaching between Yuri's legs to get there in time to demonstrate,

"You take something slick-- I've got vaseline-- and you work it in, here," the pads of his fingers brush the ring of tight muscle, "until things are relaxed enough that you can have sex like that." Presuming Yuri's got the same look on his face that Otabek did when he read it, he keeps going, "I thought it sounded stupid but I tried it out the best I could in the shower and it's not bad. A little weird, but it doesn't really hurt or anything."

Yep. Otabek not only managed to do research on how to have sex, he tested it out first. He doesn't say it like there's anything weird or remarkable about it. It just seemed to make the most sense at the time.
