Drink s red bull last night and could not have sex wiith my new girl friend. I am having erection problems?

Red Bull. It's hard to say without a history and physical exam , any meds you may be taking or chronic medical conditions. Is this your first experience of ed(erectile dysfunction)? My suspicion is that , without any other existing problems, you experienced excessive anxiety from the red bull's caffeine. Anxiety will impair normal sexual arousal. Try again without the bull.
