Can any doc tell me what's the best way to sustain erection?

Here are some... The reliable way to maintain erection is good health + judicious use of PDE-5 inhibitors like Viagra or Levitra or Cialis if the degree of ED is mild to moderate. Regarding more details on ED, peruse articles listed in http://www.formefirst.com/onSexLife-ED-CareOptions.html. More? Contact me at www.healthtap.com/dr-Lin with RQPWJC to log in for appointments.
