... and I don't mean the naval vessels
relationships between characters, original characters in particular
It's usually a weird subject to talk about since so many people take their characters very personally, so just to be safe, ponysonas, gemsonas, fursonas or whatever other *sonas or avatars are excluded.
As some of you may know there is a very special OC in my collection that I have a special connection with. it is of course Adalbertus, the vampire lord general, but since he's kinda sorta my avatar, he is excluded from this discussion.
So lets talk about the third most developed and the most recognizable character, Amber Drop. Over the years I had RPed her few times and she had few (non-canonical) romances as a result as well as few alternative versions of her that were created for stories written by my friends. Most of my other characters also had their own share or romancing, relationships or other interactions, be it in RPs, RPGs, in their backstories or in stories written by other people. I also created characters designed more or less explicitly to interact in that way with other people's OCs, or sometimes characters I created for some other purpose ended up in a relationship with someone's OC.
For me it's all for fun of telling a story and interactions with other charterers. I play and host RPGs and I really enjoy telling stories or making up scenarios I drag other people into just because I know they would like the experience. So even if I decide to play a character who fall in love in some other character, or someone who fucks everything that moves and breaths, it's no different for me than playing a sociopath who shoots first and usually doesn't bother with asking questions. Those are characters I control, be it in an RPG scenario, an online one-shot RP or a story I develop with friends and emotions my characters feel and actions they do are just a part of the fun.
But I've heard opinions that for example one should never romance someone else's character if it's outside of the real life relationship.
so... I'd love to know your opinion on the subject
Do you have any characters in any fandom, or completely original, that you 'ship' with other characters that do not belong to you? Would it be awkward to for example RP an relationship or an outright sex scene with your non-romantic friend controlling his OC, or are you okay with it? Do you have characters that are in a relationship and if so, how does it work? is their relationship their defining characteristics, or are they themselves developer as characters and their relationship is just an organic result of that?
If you yourself are in a relationship, did it occur to you to ship your OCs outside of said relationship? Would you be jealous if your partner did it in an RP or had a character in a relationship with an OC other than yours?
