Priyatā-rati प्रियता सति

as from Bhakti rasāmṛta sindhu भक्ति रसामृत सिन्धु: 

mitho harer mṛgākṣyāś ca sambhogasyādi-kāraṇam |
madhurāpara-paryāyā priyatākhyoditā ratiḥ |
asyāṁ kaṭākṣa-bhrū-kṣepa-priya-vāṇī-smitādayaḥ ||2.5.36||

Priyatā-rati:
"That rati found in the doe-eyed young cow-girls and which is the root cause of eight types of enjoyment between the eternal young girls and the eternal young (14 years old) Kṛṣṇa is called priyatā-rati. It is also called madhurya-rati. In this rati, there are sidelong glances, moving the eyebrows, affectionate words, slight smiles, etc."

yathā govinda-vilāse ciram utkuṇṭhita-manaso rādhā-mura-vairiṇoḥ ko'pi |
nibhṛta-nirīkṣaṇa-janmā pratyāśā-pallavo jayati ||2.5.37||

From the Govinda-vilāsa:
"For a long time, Rādhā and Kṛṣṇa have been longing to see each other.
All glories to the new sprout of hope of being able to see each other alone!"

yathottaram asau svāda-viśeṣollāsamayy api |
ratir vāsanayā svādvī bhāsate kāpi kasyacit ||2.5.38||

"These five types of rati (from śuddha to priyatā-rati) become progressively
more blissful by increasing tastes. The particular taste arises in a devotee
according to his previous experiences."
