🍆New vibrator help 💦💦💦

Ladies so I bought this new bad boy and I’m really new to vibrators that go inside. Anyone have this one and want to give me tips on how to use it? So this is one is for the G spot but I read you should go after the G spot till after you’re aroused so I should play with my clit first then go after my G spot. Now I was confused where my G spot was. I put it in but I felt like it was just playing with my wall and not the G spot. The head moves and does the work for you so should I move it at all like thrusting it or just leave it in there? I’m so confused. HELP
