erectile dysfunction
"I am in my mid 30's and take 5mg daily. I start a day before I know I will have intercourse so I have more in my system. It works alright. I am not fully erect on the spot. It does take stimulation. I definitively get the facial flushing side effect. Does not bother me much. One thing I did notice is I am constantly at a semi erect state. So I know it is working because more blood is going to that area. Its always nice knowing you will get erect and not having to worry. It is good stuff."
