My guy is 46 and we have had until recently a more than healthy sex life, all of a sudden despite being willing he looses his erection during intercourse, he saw a gp who said it could be narrowing of the arteries and told him to eat garlic to help keep the blood clean!!!! He has recently bought Golden Root tablets (though he hasnt told me yet, he has a big issue with what he sees as his failings) will it help or is he wasting his money?
