Wiping Causes More Stool To Drop Out?

For the past month or so, on and off, I pass a stool, wait a short while until the 'urge' to go has gone and no more naturally comes out and I begin to wipe. 

When I start to wipe, however, more stool 'drops' out. Sometimes there is A LOT, sometimes there is just a little bit. Sometimes I need to push a tiny bit for it to exit, sometimes not. 

It's almost as if after the first lot of stool, my anus, or something, closes up and blocks anything else from exiting. I know it's there ready to come out and when I wipe, it seems to 'open' and allows the rest of the stool to come out. It's really weird. 

I have internal haemorrhoids that have come back after a haemorrhoidectomy (8-9 months ago) and they prolapse a little - I wonder if that is clogging up the anus/rectum?

I think the haemorrhoids have come back from me eating too much fibre. Not enough first time and too much pushing, too much this time - LOL. 

Think you should go to your doctor

Best advice I can give is to get a squatty potty or go better toilet stool which change the position you go to the loo in and help the bowels to empty properly without straining. Having your feet raised really does make a massuve difference. X
