anal play question

[little_woogy]

i was wondering, the thing is im able to get my whole fist in my ass, but i cant go any further, and i can never get much of a dildo in my ass. any tips/pointers or explainations as to why this might be happening. i have no medical problems, and dont experience pain whilst trying to fuck myself with a dildo

So it sounds like depth, rather than the thickness of what you're inserting is the problem? I've never been able to get much more than my hand in my ass - the video of the guy I"ve seen on xtube who goes into himself all the way up to the elbow is just unimaginable for me.
Does it hurt when you try to go deeper? What exactly is happening?
