Drinking a cup or 2 of black coffee a day affect sexual performance and penis erection?in a good or bad way? how about mixing coffee with honey?

No.: Black coffee or adding honey to coffee should have no effect on sexual function. Most common cause in young males is performance anxiety (pressure to perform, pressure to get wife pregnant, etc). Relax, exercise during the day, talk about it with your partner, share with each other likes and dislikes..... Erectile dysfunction is common at any age; if need be, seek short-term counselling.
