Please tell me I didn’t accidentally say something super inappropriate to my host brother

Some brief context: My Japanese is super beginner level. I recently did a study abroad in Japan. I was there for Thanksgiving, so I got out my sweet potato casserole recipe to make with my host family. As I was mashing the sweet potatoes, I asked my 14 year old host brother "やりたい?" and gave him the bowl, and he and his host mom seemed a bit taken aback. I normally would say "したい?" but I heard "やる" being used a lot in more casual contexts instead of "する" so I said that. Now it's been keeping me up at night because I'm worried I accidentally asked him if he wants to do… something else. I've been too scared to ask but I need to know, it's been eating me alive.
