" Yes, Pramipexole enhances libido for both sexes and in the case of males reduces or eliminates the refractory period."

If these effects were reproducibly demonstrable, controlling for placebo effect, Boehringer (it's maker) would be all over it with both feet, but they're not. They are the company that recently wasted many millions trying to get flibanserin approved for enhancing female libido. The FDA voted 10-1 that it was no better than placebo, and that the side effects were unacceptable. Boehringer would not likely have gone to all that trouble if they already had a FDA-approved drug (pramipexole) that they could have submitted for approval of a new indication without repeating all the pre-clinical safety trials.

You are mistaken. The maker tried to get FDA approval for this use but were unable to. I do not consider this particularly strong evidence that the effect is not present. Faith in the FDA as an efficient arbiter of truth is not a misconception that I suffer from.

I have very little evidence regarding whether that drug is effective. And yes, I am saying this after being informed of the FDA vote. I only consider a 10:1 vote against to be weak evidence in favor of the effectiveness of a drug for this particular application.

Boehringer would not likely have gone to all that trouble if they already had a FDA-approved drug (pramipexole) that they could have submitted for approval of a new indication without repeating all the pre-clinical safety trials.

They did.

You may find it interesting to note that under the side effects of pramipexole the maker is required to list hypersexuality due to multiple studies showing increased sexual urges and 'hedonistic behavior'.

If it causes increased sexual urges in 1 in 100 people, it'll show up in studies but be useless to most people trying to increase their sexual urges.

Completely true.

Another interesting side effect of a medication, and one which can definitely not be relied upon, is inorgasmia. While SSRIs will almost always delay ejaculation (sometimes a good thing), in some cases they more or less prevent it entirely. This makes it possible to copulate until physical exhaustion:

Um... that body part is not supposed to stay in that state for 5 hours. Maintaining an erection means diminished bloodflow to the area and anything over 4 hours calls for a trip to the emergency room.
