Since my baby was 4-5 months old, she would only drink her bottles while asleep. She is now 12 months and does the same thing.
If your toddler starts to touch himself, ignore the behavior, but direct him towards something fun you can do together.
Often when a toddler talks back, they are testing limits, which is a common and developmentally appropriate behavioral challenge for this age.

Generally, letting a toddler work through their tantrum without giving them much physical or verbal attention is ideal.
