Welcome back to the forum!
I’m going to ask what might seem to be a stupid question: What do you mean when you say “low libido”? (Because that phrase can mean a variety of different things to different people, you see.) And, “low” by what standards (and whose standards)?
And just so you know that I’m not asking this to pry or be nosy, someone could apply the phrase “low libido” to describe a situation where–say–the sex is not pleasurable for them but they don’t want to “mess up” an otherwise wonderful relationship by acknowledging or addressing how their otherwise wonderful partner might be less skilled in this department.
And another person might use this same phrase to describe something that’s due to the fatigue from adding a relationship (however wonderful) to an already busy life.
And yet another person might use this same phrase to describe a situation where there might be an emotional issue (say, fear that this relationship might end like some other relationship).
And still another person might be in a wonderful relationship with a partner who has a naturally higher drive with whom they can’t (or rather not) keep up and they might judge their own libido as “low,” when it’s the partner’s which is “high.”
Now, these are all just illustrations, to give you some food for thought. I’d offer different recommendations for these different examples, you see?
