Before I answer this. Ricky, wow, just wow. You do not talk for anyone's "spices". So I wish you would stop trying to speak for the entire male populace. Anyways a good way is to bring up the subject when talking about other people. Aka friends and families marriage. DO NOT DO IT TO MUCH. I had a girl friend that pushed so hard to get married. If he doesn't seem too interested then leave it alone. There is a good chance he is already planning out when it is time to start planning his proposal. If he wants to do it, he will do it.

Enjoy your life as a dating couple; marriage isn't everything, and doing it to soon can ruin a good relationship.
