erectile dysfunction
"I'm 52, 6' 225 lbs average to above average build and healthy. I tried as recreation while on vacation.  I took 50 mg (half pill) and really didn't do a whole lot, but I had multiple drinks and a large dinner before taking the pill.  If you read the disclaimers it mentions not to drink or eat a lot before taking the pill.  Next night I tried 100mg (whole pill) without the drinks and it worked and was able to have intercourse for about 30 straight minutes.   My wife orgasmed I was not able to. While the feeling was mostly there I just wasn't able to orgasm, which was very disappointing. But 30 straight minutes of intercourse was still fun... just would have preferred a better climax! 50 mg works best for me."
