If it's the one that is 'way down'--like just above your genitals, where the reproductive organs are--then yes.  It was never very visible on me, but I could feel the swelling right before 'that time.'  I can now press on that area and feel no resistance, like there's nothing there.  I suppose that makes sense: the last gyno exam I had at 11 months on T (*gag*, but necessary), the doctor said that my parts had shrunken to the size of what an 8-year-old prepubescent girl would have.
