I have a nicely exquisite slo-mo video. I would like it to export to my computer. 

Simply copying the file by plugging into the USB cable loses all the slo-mo edits. 
Doing an export via Share by Email seems to lose the quality (it compresses it).

I don't want to export it to YouTube, Facebook or anything like that. 

How can I get it to my computer so that I can email it to my friends?
