So, I can't really think of a lot of PG uses for this sentence ...
I'm thinking of professions where you might need to touch someone: doctor/patient, handcrafters (maybe), etc. maybe even mute people, where you have to touch someone to get their attention (and communicate)
Ok, fair enough. Let me get a winch to pull my mind out of the gutter...
I see what you did there.
In this sentence 'You touch me a lot' can means 'You affect my emotions'. We can also say 'Você mexe comigo'.
Can this mean emotionally touch, like "Your compliments touched me a lot?
Você me toca muito, que chega afinou.
and i thank you for that..
