Just 2¢ from a DYI'er of +4 years…
PG has a very bitter taste. You might try tasting a drop of VG, then a drop of PG to see how your taste buds read them. People's sensitivity to bitter flavors apparently spans quite a broad gamut.
Also, if you have been vaping only 100% VG unflavored, it is extremely likely that your taste buds are used to the sweetness of VG, and therefore, the PG tastes even more bitter. That is my situation. When I first noticed PG tasting extremely bitter, I searched on ecf & found a number of very helpful threads in the DIY section. Sorry I don't have links, this was several years ago.
At any rate, I found quite a few posts mentioning the bitter taste of PG. And I also found that many vapers experience vaper's tongue after a few months-year of vaping. cng114 suggested trying to re-set the taste buds with a menthol vape. I've had good luck with that myself. Because I am highly sensitive to PG, I had to continue using VG, but I mixed in 15% distilled water (which is really high). It did work.
Recently, however, I have had a very persistent case & I have had to reduce my vaping to almost none, and I'm still in the process of hopefully resetting my flavor receptors. Good luck!
