I am definately going to discuss it with her first...Thanks everyone for your input. I love and respect my wife very much, and I did tell her when she found out about my dressing that the hiding and lying were done with.
I do have a few reasons behind it besides becoming more feminine. I spend a lot of time outdoors in the winter and I have found that tights or pantyhose make a great base layer to wick moisture and help to keep warm. Until I joined this forum, I never realized that they fall down constantly because they are sliding down on the hair. I also wear Under Armor, but found that it is very itchy. My wife has been helping me to remove my back hair (I have always hated back hair!) for about a year now. I found out that I could actually wear an Under Armor shirt without itching. My legs still itch, but I have been hesitant mention the leg shaving. Now that she knows about my CDing it may be easier to bring it up. I am also getting a tattoo on my calf next month and will need to shave the area where it is going to be. I can also explain that just shaving a small patch would look odd, so I might as well shave the whole leg...and if I'm shaving one, I might as well shave them both.
These are all legitimate reasons, but if I were not a cross dresser, I would not even be considering it. So it does all come around full circle to the cross dressing. Maybe I should just tell her I think my mini skirt would look much better with freshly shaved legs and some new silky panty hose! Thanks again to all for the thoughtful suggestions! This is why I love this forum!
