Does the body get used to ED pills and they stop working?

[PrettyUnhappyGuy]

After radiation treatment, I was told to take low-dose Viagra for two years to facilitate sexual recovery. It's working so far. I can get good erections now four months past radiation (still no orgasms though--frustrating).

However, are these drugs similar to things like benzodiazepines where you have to keep taking higher and higher doses to get the same effect (should I be preparing for this to happen) or do they work indefinitely similar to a blood pressure med?

Thanks

Bro it takes years to be able to get an erection as per my GP. The pills don't work after a time. It's now almost 2 years and no erection at all. If u want to talk about it send you number and I will call u. [e-mail]

I was diagnosed with TB meningitis which amongst other things, affected some of the nerves at the base of my spine. This left me with ED and an inability to get or maintain an erection.

After trying all of the usual ED meds and devices I stumbled upon the penile implant procedure.

I had this procedure and can now get an erection whenever I want to and can ejaculate without losing the erection!

This is a question for your doctor who knows your history, and medical condition.
