Masturbating

Dea
Guys...so im 13 to 14 this sep. I tried masturbating not a while ago and I kinda like it if I penetrate hard... I used to masturbate only with squishing my legs together, not fingering or things like that. I still do it and thats the only way I can orgasm. I cum really easily, for ex., when I stick a finger in my vagina, I immediately cum. Can you give any advice around masturbating tips and tricks?
