Masturbation Virgin- Need Help!

Hello!

I’ve “tried” masturbating in the past but nothing really happened and that was me just failing miserably at fingering myself, like I felt nothing. Lately I’ve been super horny but I don’t really know what to do to get a release. When I try I’ll find something that feels good but I lose it in a second, and I’m just getting a little frustrated. Keep in mind I’m 17 and can’t really go out to buy a vibrator (as much as I want to). Any and all advice appreciated :)
