give me play ideas please!

My flatmates are home a lot more recently so I barely have time to play. I mostly stay in my room and only wet my diapers at night when I can avoid people more easily. I would love some advice on how I could spice up diaper play when staying in my room! i wanna try inserting the biggest object I can take and fuck myself with it untill I wet my diaper. I also wanna stretch my ass again and see if messing like that feels any different, since I havent really played with that nowdays. Any fun ideas are welcome too, I’d love to try new stuff!
