Are you a skinny person? I've read people under a certain body% fat can have lower sex drive as the body is signaling to them that they do not have enough nutrients to spare/procreate.
Could be made up but sounds like a plausible theory to me.

People describe me as "skinny" or "slender", but I've got a fair amount of muscle and still some fat left over from when I was overweight.(I dropped over 60 lbs from 2013 to 2015 and have stayed at around 160 lbs) But I don't have calipers and haven't measured my body fat percentage, so I guess that'd be a good thing to figure out.
Yeah, it's funny because I eat plenty of eggs and fat, which have constituents used by the body to produce hormones like testosterone. If anything, I'd expect the opposite effect but I haven't read any literature on the effects it can have on libido, so I'm not sure what's typical.
