These are types who exhibit paternal/maternal tendencies towards others in their everyday lives and may thus carry over these notions and temperaments into their romantic life. These types habitually attempt to give their partner what he/she "needs" (or what they believe they need). As a result, they may become drained by lack of attendence to their own needs and desires. In a partner, they are searching for a combination of strength and gentleness.

If I were to describe this type's approach to love, it would be "serious." He approaches his love interest almost with the intention to "teach." This can quite possibly rub the object of his affection in the wrong way, possibly interpreted as condescension. Like the childlike type, he may tend to live "outside sexuality" and may have to intellectualize it in order to be comfortable. He is looking for a worthy pupil.
