Cheap alternatives for a desperate teen

Cheap Alternatives

So I‘m a young teenager exploring my body and finally want to experience a p orgasm.
I tried a dildo for over 2 Months and it doesn’t do much.
I leak pre cum but after 1 hour my ass just starts to hurt from the constant penetration.
I used my E-Toothbrush a couple of times as well and it feels much better even though the vibration is wayy to small.
Using my fingers I can stimulate my prostate pretty well but they eventually get tired without me having a proper orgasm.
So I wanted to ask for a cheap alternative to an aneros or prostate vibrator because I can’t really spend that much money on sex toys and my parents would probably notice.
I really would do anything to get my hands on a good and powerful prostate vibrator.
