Normal Training is something you might expect in a training session. You can touch yourself when you see pictures including what you want to be attracted to.
It probably requires some attraction to the pictures you hope to be attracted to. Without that, Beginning is recommended.

So it is natural to use Normal Training sometimes even when you have a stronger attraction. Normal Training also allows you to use phrases.
