Viagra
"I'm 76. Been using Cialis for BPH and also ED. Tried Viagra last week. Wow. Never performed so well. Took about 2 hours before sex. Had a great erction and lasted as long as I wanted to. Decided to climax after about 1/2 hr. of continuas intercourse. My partnetr was amazed and said it was the best! I had received 50mg tablets, but I cut in half. Seemed to be more than enough. Maybe I'll try 50mg. for comparison."
