[serious] Reducing libido slighttttly for increased focus

For those of us that have high libido, I would imagine that this can sometimes cause a distraction. I have a very high libido and I feel like it definitely impairs my concentration multiple times a day. Is there any safe way to slightly reduce your libido?

I've heard that propecia can do this, as it's a possible side effect. I also have some hair loss and slightly larger than average prostate for my age, and propecia main effects target both of those.

So I'm not really looking for a nootropic in the traditional sense, but if libido is causing me cognitive impairment indirectly, I would say what I'm looking for is still related to nootropics.

EDIT: pattern in the comments has been that if someone suggest a nootropic that decreases/increases their libido, another person will reply and say it has the opposite effect for them.
