Pretty much as the title says. I’ve been anal dilating following for a while with the future method silicone set and I tried my 5.5in insertable dildo as the next step up from them. The dildo itself is more flexible than the dilator set. The girth is not a problem but when I put it all the way in I feel a point of resistance. Initially I was on my back with my knees to chest to try to straighten the rectum and it alleviated slightly but still felt it. I then tried inserting while on all fours while arching and it again alleviated slightly. I know the rectum and RSJ don’t contain normal pain nerves and I never felt any intense discomfort just the poking. I also read somewhere that the upper rectum doesn’t stretch quite as easily as the lower rectum. so how do I know if I’m hitting the rectal wall or the RSJ?
