Let it happen, she'll get bored and go away(unfortunately). After a few hours of my first time reading the succgen thread I started feeling light touches across the skin and a presence in the room. She was with me appearing and disappearing for the first 2 days and then after she appears fairly infrequently at her own behest for whatever a succ wants from a man. She just recently told me her name too. However all of this only applies if u didn't actually do the ritual in the thread, if so then you got wat you wanted I suppose.

Very true, it does not take much to suggest even a mild interest. As to their intentions, I have heard it claimed that it is for carrying out creating by way of surrogates from both men and women, but I have no evidence or experience to confirm this. 

It is possible the term we attribute to them may be an archetype of actions, perhaps those wishing to live out desires of a sensual nature with a willing partner.
