I have some questions about anal gaping and thought that putting them here was the most appropriate. I would also like to know where else I could post these bullet points to get advice from. Any and all sources to these questions would be appreciated

-How long do I have to keep my gaping tool in for for my ass to keep the stretchiness until the next session?

-How long should I wait for until the next anal training session?

-What tool works best for anal gape training?(Such as an anal training kit, butt plugs, dildos, speculum, ect)

-Do I need an enema every time? (I have heard taking regular enemas is unhealthy)

-How to I go about deep anal training?(I can take it deep with my skinny dildo but not with the thick ones)
