Gohan probably just wasn't strong enough during the three years before the Androids for his body to handle Super Saiyan, but by the time the Room of Infinite Bullshit appeared, Goku saw an opportunity to really focus on his training and get him there.

...or, at least, that would have been my theory prior to Goten and Trunks achieving the transformation practically at birth for absolutely no reason, completely skipping the power requirement and emotional component that leads to Super Saiyan.

Goku had to watch his best friend get killed in front of him; Future Trunks saw his entire world destroyed and his mentor slain; Vegeta was faced with the reality that his dream had been stolen from him and he couldn't keep up; Gohan achieved it due to his own rage and self-hatred about always having to be protected by his friends and never doing the protecting.

Goten and Kid Trunks? Well, Toriyama couldn't be bothered to put them through any kind of character arc at all, so they just had it when they were about six years old. I guess they must have reacted very poorly to being grounded or something.

You should see how Super Saiyan is treated in Super. Kale and Kefla learn how to do it because they figure out that all they have to do to turn Super Saiyan is to flex the muscles in their back, and BOOM transformation.
