Erectile Dysfunction
"I am a 36 year old male.  From time to time I have a problem maintaining an erection when engaging in sex.  No problem during foreplay. My doctor wrote me a script for Levitra and it was amazing.   I was 16 again and a  superman in the sack. I did have a feeling of congestion and occasional headache but is worth it.  The down fall is that you need to know in advance when exactly you will be sexually active.  So much for romance and spontaneity.   It is also very expensive."
