Tips on masturbating

Shay

So I've been having a lot of trouble to have an orgasm from the g-spot sine my hands gets tired for idk what reason. I lose rythm for idk what reason it's annoying me bc I feel close to an orgasm but then my hand gets tired and when I'm the process of switching hands I have to start all over again. So does anyone have any tips? Or something bc I've been struggling with that for a good 2 years

Im 17 and a virgin btw.
