"Is viagra or manforce 50 or 100 mg safe for diabetic person if he takes occasionally like once in a month? But every doctor gave me irrelevant answers like which drug is used in this medicine or what's the purpose of this medicine or what is ed and how can it be treated. I don't want to know all these things as I already knew I just want to know 'is it safe for diabetes patient to consume once a month? I take it so that I can discharge multiple times during intercourse without losing hard core erection. Without this medication I am only able to discharge two times with proper erection but with this medicine I don't lose erection and I can discharge 3-5 times. I only want to get answer from expert allopathic sexologist or diabetelogist.
