Seriously need some help...What is the best way you have found to masturbate?

I masturbate and orgasm with clit stimulization. I've tried to penetrate, but I'm so scared. I've never even tried a tampon and I've had my period for 8 years now. Do you think of something to get horny, do you use a vibrator (I don't have one, should I get one?), etc? I need some tips to go solo!
