Older SO sex drive

Looking for some help or feedback,

Are there any ladies in here with a 40-50 year old SO? How is there sex drive. I know not every person is the same, I’m sure his cholesterol medicine may have a factor in it. But am I the only one whose so has a low sex drive? He wants me to initiate 100 because he just doesn’t think about sex that much anymore. He tells me to not take it personally because it’s not me. He just doesn’t get hard like he used to. I have to aggressively initiate for him to be in the mood. Just looking for some advice. Or comfort.
