Sheri’s Courtesans understand men afflicted with Erectile Dysfunction may need to take Viagra, Levitra or Cialis oral prescription drugs. Basically, the drug taken approximately 30 minutes prior to sex will dilate the penis’ blood vessels allowing more blood flow to be absorbed by the spongy tissue thereby assisting the erection; however, a man must be sexually aroused for the medication to work properly. This medication should only be taken under a doctor’s direction and never take more than prescribed. It should not be taken with greasy foods, caffeine, alcohol or other medications since that may affect the desired result. I usually take it at least two hours after a meal or on an empty stomach 30 minutes prior to sex. An erection will last up to 4 hours or until a man climaxes. It lowers the blood pressure so it is important to note that if taken in conjunction with blood pressure medication it may lower blood pressure to a dangerously low level. http://www.viagra.com/
An alternative medication is the Prostaglandin penis injection that in my opinion works more effectively than oral drugs; however, it should not be taken along with any other E.D. drug. http://www.ustoo.org/PDFs/Injection.pdf
