Practicality:

- No conflict sentiments / privacy for this kind of treatment
- The masseur's appearance has no importance

Or, your arousal:

- You would like to fantasize during the massage
- Adds mystery during the Tantric experience
- Etc.

And I ask you to express your pleasures with words, groans or quick respiration and your brain will hear you and you'll become excited.

If you believe that hands and fingers can see, well you're right… but what I see of a woman's body is only beautiful things… so let me paint in my mind the beauty of all your feminine attributes.
