Meh. I'm skeptical about herbs and spinach and lemon peel and stuff having any significant effect on a person's sex life. Unless a sexual aid has been through clinical trials of FDA rigor, I wouldn't spend the money on it.
Also, 2 minute long orgasms? I find that difficult to swallow.
Er, so to speak. 
a woman can have a much longer orgasm. I was with a Tantra instructor that taught me yoni massage... she was amazing, she taught me all the techniques. When properly aroused, she would have 'body wave' orgasms through g-spot stimulation which she made last for 15 or 20 minutes and then the finale - the clitoral orgasm... amazing!
As far as herbs - don't count them out - I have found a formulation that has me like a 20 year old - yum!
and the FDA - if a substance cannot be patented it has no way to recoup the costs of these trials - herbs cannot be patented. Isolated active ingredients of these herbs or plant compounds ARE able to be patented and that is where lots of our pharmaceuticals come from. Herbs can work as good or better - I used to react to Viagra and others - not with the herb formula. And I would NOT be hobbying 3 times a week if I wasn't getting a LOT out of it...
not that I NEEDED it (LOL) - back then it was one of those things you just HAD to try...
for me when hobbying - 90% of the time when the cover went on the tool went limp... long story short... last November I first tried this new herbal formulation from a friend in the business... the cover has never been a problem since...
