Penpals

I just recently watched Naruto and Naruto Shippuden and through the whole course of shippuden I felt as if there was something between Naruto and Sasuke. I read discussions about it and a common line was "fujoshis make up ships that do not exist just for the sake of yaoi". I also read some analysis about sasuke being either gay or bi which actually made sense.

Yes I'm a fujoshi but I've never really shipped two male characters in an anime which wasn't bl (let's leave out Kuroshitsuji aka Black Butler where I don't really ship characters but I do think that there are bl undertones)
What do you think of it? Does Sasuke actually love Naruto? I could list plenty of things I've observed but let's start.
