Oh cool, we have the same toy! here's my tips for anal: 1. plenty of comfortable lubricant. I used a simple water-based lube and it's nice for me. 2. move slowly! eventually once you're used to your toy it'll slide in fairly easily, but when starting out I'd recommend slow insertion to prevent pain/injury. 3. ALWAYS use clean toys. I wash mine with warm water and a gentle soap. honestly, anal is fun and I hope you have the best time!

Relax. Relax. Relax. Too much lube is never enough. Start with smaller things, like your fingers, and work up in size. Douche.
