Fingering Help

I (18M) have been struggling with anal fingering. Whenever I finger myself, the best I can get is pre-cum leaking from my clitty. I'm leaning towards becoming a sissy. The bad thing is I can't get myself any dildos, plugs or stuffs since my area is remote and been banned from sex toys. What should I do, I'm getting sexually frustrated. I'm closeted as well so real dicks aren't a option for me.
