Could the woman be Venus? Venus (Goddess of love) and Cupid (her son) are frequently depicted together in art and mythology. The woman in the Lovers isn't a beauty as you'd expect Venus to be, but the tarot artists that created a lot of the early woodcut images aren't known for their artistic refinement.
Interesting comment since, in the realignment of the astrological correspondences to the Major Arcana that I did as an experiment, I switched in Venus for Gemini, since I figured she might as well be doing the honors rather than her son. Venus in astrology has to do with values as well as love, so maybe the man's values are being put to the test.
