The conflict of this would be "__not__ all of me is accepted as who I am". When you look at the biological themes implied, this is mainly about self-worth, but triggered (in the case of resolution by kissing) by skin or intimate contact, or loss/lack thereof.

First kisses among teenagers are not about romantic love? I wonder what would be, then? First kisses, in many cases, are about __awakening sexuality__.
Whereas the typical __mother's love__ is about loving their child no matter what (unconditionally). Biologically, in humans this is needed because a baby is still totally depending on their mother to assure survival. Childlike characteristics are perceived as cute, we feel the notion to cuddle and protect. A mother will feel this even when the child is disfigured (or in later days when it misbehaves). Family ties also play a role, therefore ((Circulatory - Blood|blood)) affections do make sense here.

The need for "unconditional love" - being accepted no matter what - as a conflict theme reflects a __dependency that does not match life as an adult person__. It is contrary to "standing up for myself" - actively resolving self-devaluation. Among humans,__ to be accepted (but not necessarily loved) for who and what we are is an essential thing, as we are "herd animals"__. For that, the "__((Endocrine - Pituitary Gland - Posterior Lobe|territorial constellations))__" are supposed to be strategies to coordinate a community, facilitate role-finding, and to provide individual coping strategies in otherwise unresolvable conflict patterns.

This is why such a virtue as unconditional love is in __religious belief__ also assigned to God/Jesus etc., to individually __resolve conflicts on a level where humans aren't able to__. People being in "((Circulatory - Coronary Veins (intima)|postmortal))" or "((Respiratory - Larynx Mucosa |levitating))" constellations are, from the perspective of the "biological laws", especially resonating to religion and spirituality.
