Beginner tips needed

I’ve just started experimenting with anal play after becoming bored of normal masturbation. I’ve only ever used my fingers with a condom on them and have never felt any pleasure, I’ve only used anal stimulation to aid my external penis orgasm. Where should I start in order to feel pleasure from my ass and prostate before I go out and buy an Aneros product. Any tips are much appreciated!

Edit: I also am 18 and still live with my family so purchasing any toys is something I’m not too keen on. However I still have plenty of home alone time to explore and experiment.
