So I went down on my boyfriend today and it had a strong taste of metal?! It's never tasted like this before... it wasn't exactly a 'bad taste' but it wasn't good either... it was literally like I had coins in my mouth... he usually doesn't really have a taste...
He's started drinking lots of vitamin drinks one of which is zinc and magnesium can this cause the taste? Afterwards it even left an odour of metal in the room.
