My experience is that a lot of times my H needed a lot of friction to O or took too long to O. Sometimes he couldn't O without going in and out very fast. Then, if his mind wandered, this would go on for a long time. Without some additional lubrication, yes I'd be in pain till the next day. I never understood why he had to have that much friction.
BTW, I didn't mind being sore. It was a good sore. But it definately made me wary of ML again the same day. Specially since I knew a second time would probably mean he would take even LONGER to O and that it would make me even more sore!
May it be eternal while it lasts.
