To me- it's not an absolute of numbers. It's NOT a competitive sport. and it IS all about comfort or that degree of desired DISCOMFORT that melts us in good ways. Well there can be a self competition with our "Personal Best" or a lover's encouragement to seek pleasures. It can be a romantic scene of seeking what can be done. by mutual desires. Or just being in hot sweaty lust to get THAT all the way in just because it can be done:} It's been just that for me a lot- I am WANTING it in me and even if it takes me all night or many tries- It's that personal challenge that defies all else. I'm not talking about "teh stupid" fictions like getting the doorway bollard of a walmart in one's ass. Or any other such no way will anyone survive it undamaged object either. There's a few companies making silicone insertable objects that yes- someone HAS succeeded in inserting them rectally or vaginally but US doing so may never happen.
That said? We've a three dimensional object being inserted into a space defined by how far we can expand it before hitting a limit. Limits of flesh's resilience and our pelvic bones. Violating those limits can be a Very Bad Thing. Up to fatally so or just horribly painful and possibly a LASTING painful sort of damages. Detailing them has been amply done by my betters. My restating of the should be already be redundant for folks "here" is done as framing WHY. I've developed my approaches.to how I explore my anal sexuality and SENSUALITY based on most of my life having been into suchlike. Cancer's afteraffects have left more of an impact on my ass than a life time of dedicated limit pushing. so YMMV indeed applies as damages can occur from one careless session or NEVER in a lifetime.
I want no one to be hurt.
Other than perhaps our cherished realms of hurts.. so GOOD.
And that's about the non-detailed wrapup overview/intro. On to the sharing my hope it helps stuff..
Above all else- I'd place being totally into the "Headspace" for limit edgy sexuality as a make or break our ass element. I'm balancing my tendency to poesy with the realities of what we're doing to our selves and/or our lovers. So yeah, it's simply GOT to be all psyched for these rides or it's more liable to go not well. Once I'm psyched for a session of stretch- it's also to me at least- imperative that I have been totally cleansed all the way up to at least my cecum. Ideally for this play- we've done our comfort levels of juice fast and enemas repeated till we're sure there's trivial to zero chance of feces. It's not just for a healthy aversion to scat. It's so if we ever did have any damages- the absence of feces can be life saving. sorry for buzz kill but scat and death are both their own buzz kills.
I call my enemas till clear for a good ass play session - Self loving foreplay. It's also entangled with the deep psyching myself for a deep insertion. .
And now it comes to the how big and how. Ive found that situational of set and setting type details affect how a given session goes. MORE than any other
sexuality. As this is a whole body ride. I often begin with a slim vibe or the handle of my prostate massage wand. And Ive used my proctoscopes or just vaginal cream inserters.. to get lube DEEP in me at a session beginning so it can be removed from worries.
Lamaze breathing or whatever relaxation rituals of similar type work for you are an enhancement. Lamaze's had me take huge things seemingly effortlessly.
1 liter soda bottle's about the largest and to the base. .
Positions another YMMV and sol personally subjective as to defy commonality too.
