I’ve spent some time contemplating taking finasteride. But of course, in light of the side effect profile, it has deterred me greatly. But one day, I decided to take the plunge and try the drug. On the first day, when I was having intercourse with my girlfriend, I lost my erection, right in the middle of it.  Is this a placebo or is it real?

I have seen young men talk themselves into the sexual side effects of finasteride. These young men tell me in the office when they get the prescription that they know that they will become impotent. Knowing the outcome makes it happen almost 100% of the time and this is the placebo effect which is very powerful.
