EWCM is quite thin (like water but a little thicker) and stretches a long way. It can also easily be confused with sperm which tends to be more globby and sticky. If you have DTD in the last 48 hours or so, it could be that as well.
Bahahahahaha!!!! Definitely have NOT DTD in the past 48 hours... ROFL
