A lot of guys use medications such as Viagra, Cialis or Levitra to help them have harder erections that last for longer during sex. And guys who are using crystal meth, especially long-term users, tend to use these erection enhancers a lot more often. Also amyl is a popular drug to use before or during sex to help relax the anal sphincter.

Mixing these three drugs together is very dangerous and you should avoid it. If you’re using crystal, you’re likely to have much longer sex sessions, often with multiple partners, and unfortunately using crystal makes you much more likely to take risks such as not using condoms. So the risks of contracting or passing on HIV or other infections is much greater. In fact using Viagra and amyl together, even without the crystal, is a bad combination, as it lowers your blood pressure and it can be deadly. So mixing all three really is to be avoided if you want to survive the night!

Everyone knows that using crystal can eventually lead to “crystal dick”, where you end up needing both crystal and Viagra to get an erection. Using these drugs in combination with HIV therapy is also dangerous as they can have a stronger effect.

But it’s worth considering that there may be other reasons why you’re taking these drugs. Are you using crystal because you’re depressed? Might an antidepressant or counselling be a better choice of treatment. Your poor erections could be the result of low testosterone or even diabetes. It’s worth talking to your doctor about it.
