Agree, Agree and Agree.... To what? Well true friendships can be between opposite sexes, my best friends are female. I certainly believe friendships can be born digitally, assuming people are honest and genuine meaning the same or more or less the same as in real life (and many are I would think). In the future we will have virtual reality implemented in such a way that we will be able to experience virtual life as in eg the movie Inception, as real as if you dream. Then all the elements are there, like visuals, body expressions and the emotions that comes along with it. But we are not there yet, but still, you dont need to see each other to be able to connect on a mind level. I didnt had the experience bring virtual 'friends' into my real life though. I do however develop a good friendship with someone I know briefly from real life (cannot call it friends) and with and around Steemit we communicate so much that I can call this we becoming good friends. It is a she BTW :)

Added to that, digital communication and FB, chat Apps and all, helps to stay in contact with those I met maybe for just one evening at some event and enjoyed a great day and/or night. I have several examples that because I stay in touch through digital means we meetup (even if this is once every couple of years) when possible or in one or two occasions even a kinda vacation together (mostly people from other countries, so there is logistical challenge).

BTW true friendship for me has no distance, and has no time, and has no "we need to see each other every week, or talk to each other every day". I have some friends living in NL who I see maybe 1 or 2 times a year. BUT still, they are my true friends, when we meetup it feels 100% comfortable to be 100% one self, as if we meet just a week ago. They will be there for me when I need them, regardless! That is true friendship for me!
