Don't worry, be happy. You are free to put either foot in front, and since you don't feel like you have a definitive favourite it is quite likely you can do both. Some people will feel that wrong way is completely awkward for them, but others may feel it doesnt make a lot of difference. If you look to snowboarding, you can see that riding fakie (back end of board pointing forward) is a very common thing to do. Snowboards are quite symmetrical around the middle, there are no fins on one end. Riding fakie is effectively switching the lead foot. I do not find this impossible. It is a brain thing, and it is possible to learn, but it is obvious that some people do this naturally, while others struggle to do the switch.
You may be the lucky one out here, just get up on the board and go whichever way you want. I have been playing around with switching on my longboard, as in starting left foot forward and then do a little dance to turn my body other way round. Results> quite a few holes in the water, but I managed... once

If you want more tips on how to find which is better to put forward, mine (left) is the one I stand on when I shoot penalties in soccer. In soccer there are some people that shoot almost equally well with both feet, but that is not me....
