I am from the UK so you will have to excuse me if I write something non american but I do try and write in character but can get it wrong and don't mind being told
I am new to roleplaying supernatural but from reading and writing fanfics I like angst, hurt/comfort, Romance and prefer some action between the boys, I enjoy writing NC17 and don't mind getting right into it but usually I like to take sometime getting to the sex scenes and let the tension build. I am not a fan of parent abuse, rape or the boys with anyone other than eachother oh and never really got the whole male pregnancy thing
I think I could see myself playing either Sam or Dean, but I would probably find Sammy easier to write as I am more like him but that said I love Dean and I am up for the challenge of writing him. I don't mind playing top or bottom for either character but top Dean is usually the best way for these two.
I guess that is pretty much all I have to say, I am away for a few days but intend to start writing when I get back and if anyone wants to write with me just let me know.
