Men’s health vitamins


My husband and I have never had a problem getting pregnant. We’re trying for our third now and he’s having delayed ejaculation problems all of a sudden. He can come, but it seems to take forever. He says it’s because he’s getting older, but could have something to do with his stressful job too. Either way, does anyone know a good vitamin/supplement for men’s fertility health? Or to help with his sexual stamina? I don’t think we really want to try anything too intense, but just like a daily vitamin. Any suggestions?
