So a medication I take increases libido. I already had a very high libido.

What helped a lot was having an iron will.

What helped more was having that will forged into steel by having my hand and arm injured. I have become like a monk now at holding it back and keeping focus.

Bonus points I can now basically get through pain or missy anything through sheer willpower alone (note: this could be a bad thing too, like not throwing up when you ate something bad and should have).
