You can also try shatavari, this is an Ayurvedic herb known to be a great female reproductive tonic. You can use this at the same time as maca. I don't know if it will boost your sex drive or not but it is used for this condition. Banyan Botanicals is a good brand for shatavari. Herbs can really vary so much in the quality and effectiveness. Ginsing and Ashwagandha are also herbs that work in a similar fasion to maca, don't know if they would be helpful for you or not but you could try them and see. Wish you all the best, good luck.
