Too Deep

Yes. After you get in past the rectum, the sigmoid colon bends around. Everybody is different, but in some guys the curve is such that the end of penis sort of gets stuck in the bend. I'm not all that long (about 8"), but I've had some guys tell me it hurts when I go in deep and feel my cock "bottoming out" in the bend.

It's true that guys who get fisted get very deep penetration, but there are some differences between that and getting fucked:

1. Not everybody can be fisted particularly deeply.

2. The fisting top bends his fingers to ease his hand around the bend, which a hard cock will not do.

3. Guys who get fisted deep usually take it in just once or twice, which is very different from getting relentlessly pounded when fucked.
 
Please tell me what is 'Mr. Hands'

Several years ago I was experimenting with a 12" flexi dildo,
had about 9"inserted which felt very uncomfortable, no pain but
realized that was as far as I need to insert the flexi dildo - removing
it slowly felt very good and it was then I knew I would like a big
dick up my ass. Have not experienced this again at any time but
8" of real dick has sent me 'spinning' for hours after.

The play and pushing the 12" slowly was fun and discovery but once inserted
to the max length was when I felt discomfort. Never did this again.
 
Who's Mr. Hands?

I'm not posting a link (not hard to find with google) but he did a video called two guys one horse where he took it deep from, well, a horse. Rumor has it he died several hours after the video was shot from a ripped intestine or something...
 
Of course! I can barely go pass a 7 inch dick... It just starts to feel painful... It's surely hitting something wrong.
 
yeah, it kinda starts to feel like it can't go any deeper... it doesn't hurt but I certainly feel discomfort.
 
dont do it guys! (this will make the hung guys smile)

if you ever get pass that point, its the most amazing feeling ever. your ass will never be the same again and the other "shallow" fucks wont be enough for you!
