That is highly abnormal for a 28 year old male. Having a physically low libido and sex drive (medical condition) is 100% different than not being a slave to the p*ussy (proper mindset for a DJ). A continually low libido if often a sign of an underlying physical condition and in some cases, psychological condition.
There are many parts to the male sex drive but the number one moving part is testosterone production. There are many factors (you both control and cannot control) that determine how much T is produced. I'm over 45 and still have a strong sex drive. I'm on no meds and exercise a lot and have a healthy lifestyle, though.
Having zero sex drive is nothing to brag about, OP. You should really look into the reasons why:
