There are so many products available over the counter. You just need to find one that it suited to your unique needs. If it is stamina you are after there's an ayurvedic oil that worked wonders for a number of my clients. You apply it at night (every night, even those nights that you are not intimate). I have to admit that i did not research the ingredients so i can't explain how it works, but it worked. It is called Magic oil (for obvious reasons). If you are based in the Johannesburg area then you will find it at the rosebank flea market that's open on Sundays. it is at the stall that sells himalaya products.
