My sphincter was too tight 24/7 : (((. Nothing could go in without applying a great force and no position and no lubricant and no "baby size" changed that fact :(
I needed to cut my sphincter TWICE to relax it and still - it is strong

, but somehow my fissure closed (KTW !!!!!!!)
I remember once spending half an hour trying to apply baby glycerin suppository lubed with KY gel AND Vaseline and after finally somehow managing to apply it - when I got up it was ejected AND projected across the bathroom

LMAO - that is how clenched that idiotic thing was !!!!!
