my husband is 47 yrs old, he is obese and drinks a lot. Recently has started urinating very frequently getting up about every 2 hours at night and going every hour during the day. When he has the urge to go it immediate and he can't wait. He also says he is really thirsty he's had heart burn and has been drinking a lot more liquids. I've also noticed that sexually he is ejaculating really quickly. I know he needs to go to the doctor but I'm wanting to know how quickly he needs to be seen and is it necessary to go thru his primary doctor or should he just go straight to a specialist?
