Non-con

You may be looking for the Canadian science fiction con, NonCon or the Florida Mark Lenard con called NonCon.
Non-con refers to non-consensual sex in fanworks, particularly forcible seduction scenarios. 
== Non-Con versus Rape ==
Some fans who enjoy creating or consuming such fanworks make the distinction between the aesthetic of "non-con," which eroticizes elements of non-consensual sex such as aggression, helplessness, and power imbalance, and an aesthetic that treats rape more realistically.
Other fans feel this is a meaningless semantic distinction; non-con is just a dressier word for rape. They may feel that rape should always be treated realistically or that it is an inappropriate subject for fanwork (especially RPF).
The labeling issue is complicated by a subgenre of hurt/comfort fic where explicit, but non-eroticized, rape is the "hurt" event. These stories tend to warn for "rape" rather than "non-con."
For those who distinguish non-con from rape, the difference is often a matter of emotional consent vs legal consent--non-con covers some conditions that are not legally rape (forced marriage/bonding, some sex pollen stories, offering oneself to the villain, spousal sex in some places, sex with payment in some areas), and generally does not cover some conditions that legally are rape (most notably in regards to underage, but some other issues like drug/alcohol/sex pollen lowered inhibitions, prisoner seducing a guard, etc.) Non-con deals with a character's mental state; "rape" is a term describing a legal state. Non-con can be erotic; rape is not. (The two can both be present in the same story.)
From an essay by torch: 
== Non-Con versus Dub-Con ==
Non-con may be distinguished from dub-con (that is, fic which involves dubious consent) depending on how explicitly refusal is made, whether force or coercion is used, whether one or both characters is under the influence of mind-altering substances, the pre-existing nature of the characters' relationship and/or whether the issues of consent stem from an inherent power imbalance in the relationship.
Some fans feel that dub-con is a meaningless category that should be folded into non-con: consent cannot be assumed if it's not given explicitly, and sex without consent is rape. For other fans, dub-con is a useful marker for fanworks that play with the titillating nature of (fantasy) rape without the more problematic associations of non-con.
==Some Fan Comments==
A 2000 post by Sandy Hereld: 
==Nonsexual Use==
Noncon and dubcon are both sometimes used in non-sexual contexts, such as to warn about non-consensual drug use or mind control that's either non-sexual or that the creator considers separate from sex. On Archive of Our Own, most 'noncon + other term' tags redirect to 'non-consensual + other term." 'Noncon drug use', for instance, redirects to the official tag, non-consensual drug use.

* Thinky Thoughts: Rape vs "Non-Con"; by were-lemur ("Warning: may be triggering. So I've been avoiding the discussion of rape because dammit, I know my triggers, and I'm not in a place where I can afford to be jumpy and flinchy for anywhere from a few hours to a few days. So yeah. But then events transpired, and while it's not part of the discussion (to my knowledge, since thinking about this is making me edgy enough without going back and reading everything), I'm trying to figure out the implications of a particular bit of terminology. Why "non-con"? Why not call it what it is: rape? Or maybe there really is a difference, at least when it comes to fanfic?") (June 2009)
