Need help with Grindr.

Hey all, straight masc dude all my life. I’m in my early 40’s. Very fit, active, fun, and have a huge sex drive. Over the last year or so, I’ve really wanted to hook up with a guy. I’m just not attracted to most men. I am very curious about more fem or sissy guys. I don’t know the best way to going about having an experience. I tried going on Grindr but it seems like a whole different dating/hook up world than I’m used to and there are so many terms and types and labels and etiquette. I don’t know how to find what I want? Any advice? I don’t want to offend or come off the wrong way but I it’s don’t really know how to find what I’m looking for? I don’t know if I’m looking for something that doesn’t exist.
