Personally I would offer that it's less about whether or not a low libido is good or bad, but just accepting that it may be just part of who you are. The only time libido is something to be concerned about is when A) there is a sudden change which could indicate some other problem or B) when you and your partner are on two ends of the spectrum in terms of sex drive.

Not everyone is crazy excited for sex every minute of the day. The important part is accepting who you are as a person and being honest and working together with your partner so that you both are on the same page.
