I'm going to head into the doc to see about low T, but how do you differentiate between Low T and Low Interest in the partner?

I'm in a relationship and don't screw around, but I just have no interest in my partner, although I do have a relatively healthy (how does one define this) interest generally in sex.

It might be a moot point until the T count is grabbed from the doc, but I'm curious, what the hell do we do if that isn't the problem or if it's only a contributing factor?

Do you have any other symptoms of low T? Like fatigue, brain fog, loss of zest for life? Another big clue is loss of nightime or morning erections.

Fatigue, yes.
Brain fog, yes.
Loss of zest for life, yes.

I don't know about night erections, but morning erections aren't there.

Shit. I guess I'll make that doctor's appointment.

sounds like low T
