I have yet to try a broom handle. Years ago. I started to have an interest in the annals of anal pleasure. My wife started with a finger. My curiosity grew, and three or four were inside me before long. I loved it. Wanting more, I started using a small dildo, then a larger one. I moved to plugs, man, they were nice. I would wear one to work daily to see if it could be done. I loved walking around with my plugs inserted; it felt so nice. I eventually wanted more and became curious as to how much would fit. Let the games begin!
At one point, I was using two rather large dildos at once, and I even slept with them all night to let my muscles stretch. The most memorable and intense orgasms I have ever had were with her four fingers torturing my prostrate as I worked the front side. Since I know machinery and tools, I have tried several "mechanical" objects. Still, one of my favorites is a 7-8 " dildo. I am curious to know what the real flesh would feel like. One day!
Probably not a good idea especially if it's wooden as splinters of wood could get lodged into your anal passage and cause infection.
If you want to experiment perhaps get some literature from gay men's health groups or check out their websites, opting for sex toys like dildos and vibrators are probably safest ,,just remember to clean them especially if you're going to use your personal sex toy on someone else although a hard cock might be the most enjoyable option
