Do you think your seat moved recently (when you first felt yourself "sliding off" the saddle, or do you think you figured out your geometry a little better once settled into the bike over time?

My girlie bits graze the bar when I stand close to my front tube, but only gently and I'm always riding with a chamois short. It doesn't hurt, but prolly looks kinda funny to onlookers. (Hence my "who cares?" bit. Which obviously you do if it is uncomfortable!)
