The short answer: yes, they're true. The longer answer is that it depends on the specific meth you get (some doesn't do it at all, some does it more than you'd fucking believe, and you can never really tell until you try it unfortunately). I don't recommend buying some solely for this purpose, you're likely just going to be disappointed.If you almost never use meth, even bad stuff will probably kick a person's sex drive up a notch. But what's more likely going to happen is that they'll just get fixated on something stupid and not sex, and you'll end up pissed off because they're ignoring you or something.
