Ill start with that I am a man. Short time lurker first time poster. I am Trying to get to next level anal insertions. Im talking siswet and argendana and NKJ levels. Im currently at 3.5' gape and steadily counting, but cant get much more than 9 inches inside me for normal sizes (Normal meaning 2" or so) I have a snake and it goes all the way, all 2 feet of it, and focused my purchases in width rather than length so as of yet dont have much between the snake and a giant horse dick with a funny head that i regret buying as it doesn't treat my second sphincter very well, which makes me anxious because im trying to get a Hankeys Golaith to the balls. Side/ Bonus question- how likely is it to risk injuring the tailbone at these sizes? Does anyone have any experience with that? How in the hell to i train the inside of my ass to recieve those massive sizes? Do i have to buy the ten toys in different sizes but with length that it took me to train my outer ass? That being said- poppers or mind altering substances are completely out of the question of your going to suggest that- I am completely straight edge. Will post/ send photos on request. That being said I live in a place where the only thing you need a prescription for are painkillers and antibiotics. So i have been looking around at muscle relaxers but unsure as I have found 0 other information out there of others using them to success. Would really, really love input- if you read this far thankss for reading!
