I just got through reading some of your work about erection issues. Good for you for sharing that information. I just turned 67 and continue to use Cialis. I take a 5mg daily. Without it, intercourse is a huge stinking disappointment. But if I take 25 mg at one time, my boner seems to come in the middle of the night when my partner is still sleeping. Our pleasure seems to come from licking and sucking. I work out most days—hike, bike, golf, you name it, I do it. My wife is my age and is fine with our sex program. I smoke at night and consume a few more drinks than I need, but nothing during the day and so does she. I know I am at a disadvantage from smoking and drinking, but my life is good. So what about the pills? What about the natural products on the market?
