JCEM says that such a low level of SHBG is associated with smaller LDL particle size which in turn puts me at a greater risk for heart disease (pops fish oil).
Low SHBG goes along with low E. Higher FT also goes alone with lower SHBG.
Low E goes with cholesterol imbalances and endothelial dysfunction.
How is your skin, still elastic or thin and crinkly? Pinch the back of your hand and watch how fast the skin recovers. E is important for skin tone.
Your FT looks very decent. Do you have problems that match low hormones? Libido, ED, performance, lasting power, brain fog, irritability, lack of energy, passiveness.
Your LH and FST are not elevated, so your HPTA acts like it is not trying to get more action from you testes. If the testes were not responsive, LH and FSH can be elevated.
You could test for pregnenolone and DHEA-S. If low, that can reduce the production of other steroid based hormones.
