I've never had issues equalizing due to the air leaks, but I can on demand blow air out my right eye at the inside corner. I just pinch the nose and blow gently and it will leak out. Normally I rarely have air come out as I said before, but it's easily done if I want to. During diving when I do the valsalva maneuver it's so gentle that I don't think it leaks. Above water I can do it by yawning and do it frequently, again no issues.
I read it was a problem with the one way valve not working correctly and if I recall they suggested it was caused by an infection at some point in your life. It is NOT supposed to happen in normal people from what I read, and those that know me would agree...
I wonder if I should have declared that as a medical defect on the dive app? Nah...
