Age difference in a relationship.

This will probably be going allround but I just need this to get off my head..3 years ago I realized I am gay and since then I knew I was attracted at men. Older men actually. When dating another man it was always someone in his 50's or somewhat younger. I am 20 myself now. I do know people change their interest and in months anyone can change it do a different thing.Well, forward 2 years. Somewhat of 10 months ago I met a man just for a quick date. As the bloke I am I only came when I knew it was a sane man. Something happened that day to know this was a really special man. He was 41. I knew that from the start. I was 19 at that time.One week later he had his birthday, 2 months later I was 20. Since then I only dated him. When I travel to another city I don't have the need to seek contact with other man and the real thing is my mind is thinking about this man the whole day. He helped me doing my coming-out to my best friend, which was really scary because although someone can pretend gays aren't that big of a deal. My head spinned around and didn't know what my friend would think of me. One week later I came out to my family and other friends.The bond me and this man have really grow the last 10 months, I really loved him the first few months, thinking this would be my future husband. He on the other side didn't know what to do with the age difference so made it clear to me he wanted to let it be vague for some weeks, months, just to think about it and let it grow. Until today, we had a really open and serious talk about what to do with each other because the age difference is real and maybe I did think of that a little too easy. He spoke to me more often about what we are from each other (just friends or boyfriends) and honestly I don't know what to do with this whole situation. My parents never met him, know I meet him but still think it is a normal friend I hang out with. They are really scared I want a relationship with him and ofcourse I know it could change my whole life.I don't want to leave him, but neither want to spend time with him as a boyfriend to later know it couldn't work out, or regret a decision I made. Want to spend the upcoming years with him and because of the fact we can talk about any subject in any way it would be lots of fun and really helpful as well.I still like him, I still like older men so when I don't meet him anymore or friendzone him I know I wouldn't meet anyone from my own age to build a relationship with. He is perfect, with some flaws, which I can handle. Seems it just gets too close for me.Do you guys have some advice for me what you would do, what I should do, I just need some clearance in my mind what to think about it and what to do.
