It's possible for me to find just about any "type" of person attractive. I've seen goths that I thought were attractive and goths that I didn't think were attractive. Although, when I see attractive goths I think to myself that the girl would look more attractive to me if she were dressed differently.
I agree though, that the fascination with tickling goth chicks is that tickling laughter is opposite to how they look. Just like a naughty school girl acts opposite to how she looks.
I prefer a tied up and tickled school girl, but thats just me. Oh, and just so everybody knows I mean the school girl look of a skirt and long socks on a young woman, not actually a "school girl." My girlfriend has outfits like this and she is 20.
I just don't want to get flamed haha.
