 yo 

 I'm a doctor that sees men and women, practicing for 20+ years in multiple countries. There is a wide, wide spectrum here, and many, many factors, not the least of which is age. And "sex" is doing a LOT of work there. Trite to say, but communication is everything here, and thinking there is 1 truth about libido and gender is... well, wrong  

 I'm sure that's true. Butt my database is 100s if not thousands of men and women. I've had middle-aged women wanting sex daily and men who are happy with annual sex. This is just one of those things that isn't as rigid as defecation and urination. And that changes with time. For what it's worth, the doctors I know appreciate very well that hormones are important.  For my part, I just don't feel comfortable pathologizing all changes. Not that supplementing is bad, not naively assuming all bodily changes are "natural". But not every stage of life needs to be "fixed". No one claims 80+ year old men need weekly sex. Nor children. Sex is great, but we're not all on the same schedule, and that's fine.  

 I'm always skeptical it's normative statements in regards to this given the spectrum and data. But I will defend the revealed biological truth that libido varies with age and, generally speaking, intercourse frequency declines with age. But sex is behavioral, too, and tied to our values and what we conceive of as "the good life". So, yes, hormones to manipulate our biochemistry to align with what we conceive of the good life are available. I'm just skeptical and wary of implying this as somehow better or more right than couples who choose other ways of maintaining balance. Masturbating, oral sex, etc.  

 Just as you are certain you don't know, I'm certain I do. I've checked many, MANY, MANY, testosterone levels in my years. Sometimes it's relevant, sometimes it's not. The premise is the problem. I just don't see evidence that intercourse frequency is a biologically or hormonally contingent reality. It's an emergent phenomenon of which hormone levels play a part, but they're not the whole story, or even frankly the biggest part. 

 sorry, fell asleep. Valid points. Can only go by what patients tell me. I will say that I'm in primary care so see patients 3-4 times annually for years, so get to know them. And we talk about relationships and sex frequently, as it's part of health. And my partner is a gynecologist who has similar experiences to mine. All I'm saying is that there's no one right frequency for everyone nor biologically determined right frequency. 

 My high value reply of "Yes"
