Slightly off-topic, but how are you going to manage being a Sugar Baby without having sex with your Sugar Daddy? The whole sugar baby-sugar daddy relationship structure revolves around sugar daddies having sex with their sugar babies in exchange for cash and/or expensive gifts. That's the whole point of it! If there's no sex, then there's no cash or gifts.
More on-topic: yes, you can probably avoid criminal charges if you clarify with your potential Sugar Daddy that there will be no sex in your relationship. However, when you do this, you can expect potential Sugar Daddy to head for the hills (or at least to other potential Sugar Babies) because for him, there's no upside to having a relationship with you.
