Hmmm, well I don't think I would describe my experience this way (ie needing to stretch out before hand), but I will say that I am pretty sure I have be scar tissue that has impacted sex. I have had my pouch since I was 17, so I didn't have hardly any experience before I had my pouch, but I know that it took a long time (many years, well into my marriage) to figure out positions that were tolerable in terms of pressure on my pouch. If it is a new thing for you though then I would think it was not scar tissue. Overall I think my scar issues have gotten better with time.
