I've had lots of platonic male friendships.
I worked in a university department in which I was the only female. We were all young and single, and were great friends. The guys treated me like I was their little sister (I was 19), so it worked out wonderfully. We all went dancing 3-4 times a week at our favorite club. On Saturdays, we went to the drop zone because the boss enjoyed skydiving. We took skydiving lessons. We went up into the sky in the plane so we could jump out. I panicked seeing people jump out and had to forcibly restrain myself from holding them back. I'm not skydiving material.
A decade later, I worked at a college and had lots of friends (fellow profs) there, mostly male. Totally platonic. I knew them and their wives already because when I was married, my ex-husband worked there and we had lots of parties. At school, at lunch time, I was the only woman in a group of us who loved to compete by working complex math problems. It was so much fun! It turned out that all of us in the group planned to go to law school. We decided which school we wanted to attend. Then I stupidly got married again and moved to the Frozen North.
In the Frozen North, I had 2 best male friends. My Mass friend was someone I hired to replace me when I went to law school. I was controller of a company, and we hit it off, as did his wife and I. He bought 93% ground beef when it first came out (I'd never heard of it), and we all grilled out, and I dubbed them "liver burgers". They tasted horrible to me. Now I buy low fat ground beef and can't tell the difference. Besides his job, he owned a Cinnabon franchise.
My PA friend was the guy next door. I noticed flares down the road, along with a huge tree that had fallen across it. He was manning the flares, handling the situation. I introduced myself to him and we became good friends. He did not like dogs, but made up for by letting me go kitten nest hunting with him. He had a slew of cats who had slews of kittens all over his land. I wish I'd taken photos of the many times at least 10 of his cats would line up along the outside of Aidan's fence and drive him crazy.
I emphasize being totally, 100% platonic, because I was usually married and there is just no way - I have firm boundaries, and I make that very clear. I remember one time, a bunch of us were sitting around our pastor's office chatting. The topic about married people having affairs came up. I said it's a good thing we are all Christians so we don't have to worry about stuff like that. Well, most of their jaws dropped, and I was shocked. To this day, I have not met anyone who has had an affair while they were married.
