Taking larger cocks?

[1373263]

I have met a guy 8" x 6" who fills me up very well and feels out of this world good but find myself unable to hold things properly after a good session. It isn't so much that my hole becomes loose and I can't hold anything in, but simply when the urge to go comes along it pays to respond promptly much more so than before. He tells me that partners have had the same issue before and it will pass; I really want to be sure I can take him on an ongoing basis without damage and have wondered if the extra girth is disturbing things further up.
My 10 x 5" dildo has never presented this issue nor a 8 x 5" cock, either on a weekly basis- I think the girth is the issue? as I can grip the 5" dildo or cock quite tightly with my muscles- do I need to practice with a larger dildo?

Any advise please?

Total random suggestion after a quick Google search, but maybe going bigger isn't so much the answer as exercising the muscles.

It seems counter-intuitive, and I could be way off, but I wonder if doing some kegel exercises would mitigate this?

Thanks, it seems that the issue is improving as the week goes on. Hopefully this weekend's session will not present any further issues?
I have been doing kegel exercises for a couple of years now and found that doing them with a dildo was particularly effective in building muscle tone. It may be that I need to do them with a larger dildo to build strength at the 6" size- I haven't much practice at this diameter.

I'm fairly sure I can deal with the 6" girth without issue now. He fucked me deeply about 5 times on Friday, during the day and into the night. Saturday was much the same although he fucked me for quite long periods of time after a quickie in the shower; I have had no issues with urgency today (Sunday) although it seems my rectum has a greater capacity now:0
