Newb Gay Ask ‘Bout

I hardly get out but when I do it’s mainly at night bc the sun isn’t gunning me down with its sun rays lol especially here in Phoenix but last month I was out playing Pokémon go and getting in my leg exercise when I saw a dude rubbing one off on a bench. He approached me and asked if I wanted head but I declined the offer. I have a friend but he’s as inexperienced like me. He’s mentioned he said that it’s called cruising. I’ve heard and read about it but I didn’t know it was still a thing. Quite frankly I’m interested in know where I can find areas of such an activity. Hence my post. How does one cruise tho and what can one do to be safe whilst doing so? Help? Lol
