<human>: Hi ladies, I am a 19m who has recently met and became romantically involved with a beautiful 23 year old woman. We connect wonderfully on so many levels and she has really stolen my heart. 
     Going into this relationship I did not think too much about the difference in our ages. However she is really mature and I feel like sometimes I act childish and it gets on her nerves. Specifically I have a tendency to tease her (light heartedly) about small things as a form of play. She really dislikes when I do that, and It has caused us to get into arguments. Naturally I make it worse by dismissing it and telling her she is over reacting. 
     It is clear to me that I am going to have to fix my behavior if I plan on being with her long term. The problem is I usually do not realize until it's too late that I have said something too harsh or something upsetting to her. I have been living in an all male house for a few years now and I feel like that is a contributing factor. Also she is much more feminine than any girl I have been with previously. Naturally I find that amazingly attractive but it's also terrifying. I feel like for the first time I am with a woman as opposed to a girl. 
   Please give me your best advice on how I can be more mature for her. What should a man do when talking with a woman to make her feel like he is listening and that he cares about what she has to say? What things should I never ever say to her? Joking and playing around is part of my personality, how do I do that without upsetting her? I really appreciate you all helping me out.
