A bunch of questions relating to sex toys and anal

So i don't know where else to ask, so if there is a better place for this, please let me know. Tl;dr at bottom.I've been wanting to try anal for a while now, so i made a wooden dildo that is about 7.5 in long with roughly a 1 in diameter. What should i coat it with so that the wood does not get damaged (or my ass)? What are the risks of using a wooden dildo?Since i've never done this before, i also have some questions on how to go about doing this. How do i flush out my stomach/bowels? Are there any precautions i need to be aware of? How far is too far, and how big is too big? Any other tips or suggestions?Thanks in advance :)Tl;dr: have lots of questions before i bone myself with my hard, long wood:-What to coat dildo with-Any risks of shoving a wooden dildo in my ass-How to be clean/prepared for anal-What are the risks/tips/suggestions
