My girlfriend likes me dressed in feminine attire. I find it exciting and wonder if I should do it more?

My girlfriend I are both 19, and we have played around with me wearing some of her clothes. I have started to wear panties almost all the time, and it is exciting. She has taken me shopping and has helped me buy feminine things to wear for her. A few months ago I finally wnet out with her all dressed up to dinner and a movie. It was wildly exciting, and we had a great time, if you know what I mean. Now, I am wondering if I should start wearing women's underwear all the time, and dress as a girl to go out with her on a regular basis. I find the idea of this more and more exciting and stimulating. I even went out and bought myself a corset, and have tried it on a couple times, but haven't let Cindy know I have it yet. Are there other guys out there that dress up like a girl for their girlfriends all the time? Why do you think that Cindy find this so exciting for us to do?
