Boyfriend is overly questioning of things I do

I have been in a stable relationship for over a year and a half with a wonderful man. But there is one thing he does that really bothers me and I don't know how to handle it. I want to learn to deal with this correctly because we are planning a future together so I want to make sure I don't respond to him in the wrong manner. He is 58 and I am 45, and he has a fatherly, very protective side to him that sometimes is too much for me. He questions places I go in the sense that he thinks they are not safe(like the walking trail in the afternoon or the grocery store after dark). He also questioned me tonight about a natural sleep aide that I use on occasion that I get at the health food store and is totally harmless. He "preaches" alot about different things and is always giving his advice whether it is asked for or not. But he doesn't want anybody to tell him what to do. When the shoe is on the other foot, it is a different story. I feel he has other issues too, like wanting to be in control of situations that he is in, not necessarily of people. I have watched this for some time, and have come to the conclusion that the control is obtained over situations, not people. He does not try to change people or manipulate people. I have never really known anyone like him. He is very kind and honest and trustworthy, but has these issues. I guess my question tonight is: Do I just ignore these comments or tell him that it bothers me for him to tell me what to do? He is so nice about it that it's hard to get mad at him. But I know this is not good for our relationship. Help!!!
