Hey anon, OP here! Well, I'm closer to 35 too and I am actually into older guys more lol, but I really like the idea of secure/experienced Hux and newly-assigned clueless Kylo due to the power imbalance it presents.
Also, even when he was younger, Adam Driver was always more sturdily built than Domhnall Gleeson, but the age difference would provide years of experience of Hux over Kylo not just in sex but also First Order stuff, which would make even a hot-headed tantrum-ridden boy accept orders. Hope it makes sense.
