Have you started eating different? Certain foods have hormones that can effect you.

Before I say anything I hope u know if u are taking medicine that me may have an effect on your libido and also if you're not happy with your inner self have a lot to do with it. I not sure but I don't know how old you are so it could be different things like you've had a child before air parties are different it could be because of that or there's just not enough time in the day to get everything done
Is this recent or just how you've always been? Some people simply don't get horny very often or at all and others do often or even all the time. It's normal to not get horny and unless this was a recent change, I wouldn't worry.
