Staying hard has nothing to do with sex? I beg your pardon. Try to slide a soft dick in a Thai boys' ass. I am 60 and i started using Viagra last year. My doctor asked how it was. I told him "it's a fucking miracle". I started with 50 mg but I had to move up to 100 mg. Life is worth living again. I understand they are about to bring out an advanced pill that lasts for 2-3 days. I can't wait.
