is it the first chapter of this http://www.mangago.me/read-manga/dakishimetakunai/ ?
if what @801 described is the same one as what i'm thinking about, then it's not
it was yaoi but i can't remember the artist, title, or story and now it's bothering me
but one part i do remember is that the one with metal problems was going to go through a door but it started closing and his friend wasn't around to help him (i think his friend had already gone through the door..?) so he kicked the door to stop it from closing
well,is it this one then?

4) That's a Blue and Transparent Surprise
Hikari's body produces electricity, so he can't touch anything metal. His childhood friend, Ten, is always taking care of him.
That's the one !! Thank you very much ! x)
I think it was a Yaoi.
With a boy who has problems with stuff made of steel/metal. For exemple he can't pass through metallic doors without beeing electrified or something like that.
I don't remember much because I read it a long time ago. (Well, I'm even starting to doubt the fact that I actually read a story like this but it's bugging me...)
Thanks for the help anyway. :3
