I strongly suggest that before you start taking yohimbe you schedule a visit with your doctor. Yohimbe has several potential negative
side effects. I also wonder about the
long term use of Viagra and Cialis, since you started with them at a fairly young age. If you haven't had a checkup for over a year, start out with that for an overall health assessment. You can mention your erection situation at that time or then see a urologist.
