Hi, I am 43. I have this problem of going soft right in the middle of the performance. I used to be great earlier, may be age is catching up. I understand that Viagra is good option but I have this fear of side effects (may be unfounded but still a fear), and I have history of drug reactions. I have heard that there are some very effective natural stimulants are available. But I am even more fearful of bad stuff. Can anybody suggest a tried and tested natural stimulant or any other method?
