You're lucky to have male friends @faithamore. Yes they can be siblings, close friend, any activities buddy and a best friend. Some people may look at it awkward but as long you know your limitations, you trust them and they are trustworthy why not, diba?
In my side opposite naman sa sayo kasi in our friends, we only have one male. Most people thought that he is a gay but we his friends know that he is not, in fact he is happily married now and blessed with two kids.
Ahhhh so sweet. Yes your right as long us we know our limitations that's a great thought
