Need help, where to start

So I got myself an aneros because I wanted to experiment with prostate play and I know it takes super long for your body to adapt but I’m not sure where to actually start. I got a non vibrating plastic one and it says to put it in but within 30 min I get bored and take it out because I have a hard time focusing. I can’t use weed so that’s off the table. What approaches can I take?
