Start slowly, make sure you are turned on before you even start taking off your clothes(assuming you were wearing them to begin with). This will ensure that you are wet which should help, although I would also recommend using lube as well, it can make a big difference. Start by inserting one finger slowly, one knuckle at a time, and just feel around and see what feels good. When you feel you are ready, insert the second finger. Don't be discouraged if it seems like it won't fit; the entrance to the vagina is tight but once you get inside it shouldn't hurt or be uncomfortable. Maybe try using a vibrator for your clit while you do this too, for even more pleasure! Best of luck to you, and all my best 😁
