We have been together for while now, but lately he has been suffering from low libido and he can't maintain an erection. We don't really want to try viagra, although the doctor has suggested him to do so. I have heard of herbal alternatives to viagra... I have read about redrooster, vigaplus and highrize kama. Has anyone tried any of these? We were debating between highrize and vigaplus. They give a good description on their website. Highrize kama is a bit more expensive... ANY help would be great! Thank you
