Yeah... unfortunately that is not EWCM. It looks like the most perfect example of what EWCM is supposed to look like, and when I first started charting the exact same thing happened to me. I was totally like

but then found out that wasn't it.
That being said, there have been studies that have suggested that if a woman achieves orgasm before he does that it can increase the odds of pregnancy. This could be partially because that arousal fluid is similar to EWCM & semenal fluid and it may assist in the transport of sperm.
It's an interesting thought.
But, no... if you've got true EWCM it will be present during a state of non arousal.
Hope that helps...
