Curious as well, though I've experienced a few.I've got a composite with someone where Eros is part of a tight Scorpio/7th house Stellium of Saturn, Mercury, Pluto and Sun (with the Sun also being conjunct Ceres/Venus in Libra/6th. All of it's conjunct the Descendant.
I would say Eros in conjunction with personal planets lends a sort of ... sensual overlay to everything. It can be hard to distinguish desire on a very loving/base level from the relationship in general. Not impossible, but it takes a lot of mental control, IMO. Eros is very passionate, and fuels a desire to please both the self and ... well, just to please whatever Eros wants pleased.
Think of the myth. Eros loved Psyche, and although it would have meant his or her own life at stake, he still found a way to indulge in it and have what made him happy. (Until it backfired, but that might be more Eros/Psyche aspect related than just Eros).
