My boyfriend can't stay hard. it's very frustrating. is there a natural way to help him?

If your boyfriend is older than 40 years old, erectile dysfunction can be considered a risk factor for cardiovascular disease. Otherwise, performance anxiety is a common cause. A medical provider can evaluate and treat this. For natural remedies, horny goat weed is an herb that can help, but still a medical consultation would be best to assess the risks and side effects of unregulated substances

It depends on many things. Age. health and any meds he takes. Have him get a good physical and let him see a Urologist. There is no safe and effective "natural' way unless the cause is found and treated. Once that is done and treated both of you will be happy. Good luck
