First of all, welcome to the brotherhood, brother.
Second, not sure about the 2.25in x 1.5in balls. If one of your testicle is 2.25in, that is one massive ball. I can understand the 1.5in to 1.75in testical diameter, but at 2.25in, wow, that can make any ladies pregnant easy
For me, there's a deviation because of the scrotol sac layer thickness, but one is 1.5in and the other is 1.8in. of course, it's not a perfect sphere, so, the oblong measurement is a bit skew as well. If you take the oblong skewness and measure the length rather than the width, then yes, one of mine is at 2.15in and the other is around 1.8in.
