What Can I Expect When Taking Viagra for the First Time?

Question:

Dear ED: On my last visit to my doctor, he prescribed Viagra to see if perhaps it could overcome my inability to get and keep an erection. I haven’t used the drug yet, and I’m wondering exactly what I’m likely to experience when I do. I’m aware that Viagra could trigger some mild side effects, but that’s not really my primary interest. I’d just like to know how the medication will affect my erection process.
