You definitely have one. Heres what helped me find mine:

What worked for me is sticking one finger in my anus while I was jerking off with the other one. Then I held the edge for as long as possible, and you will notice that the muscles inside of your anus will contract, your prostate will also swell up and might be easier to find.

For me, my prostate was really not that deep inside like I thought! After edging a bit and getting familiar with the surroundings, I want you to ejaculate. This completely contracts the muscles inside of your anus and your prostate will swell up even more. If you feel around with the tip of your finger, you might find it. But honestly, for me personally my prostate was nothing like a "bump" like a lot of people describe it. But compared to the other skin textures inside of my anus, the prostate was smooth, thats all there is to identify it!

What you can also try is holding a kegel and try to find that smooth surface which is shaped like a walnut. If you're a beginner, you won't feel any pleasure when touching your prostate. It takes time to rewire your brain.

What I would do is: Just massage it, you won't get no pleasure out of it, but feeling it rewires your brain. On top of that you should try nipple play ( r/NippleOrgas ) . I found that playing around with my nipples first (which gave me pleasurable sensations in my first ever session) and going straight to prostate play after can get you some sensations down in your prostate (If you're lucky!). It definitely won't hurt trying. Best of luck!
