I love the term and use it myself to describe my dressing and gender identity to others. I don't fully dress or try to present as a woman, but simply enjoy being a male with some subtle but noticeable feminine traits or features - painted toes, waxed/shaved body, feminine bikini bottoms and shorts, perfume, etc. That's generally my everyday routine. I just love to incorporate several feminine cues into my otherwise masculine appearance. The term 'sissy' has definitely turned into a pejorative, but I think it perfectly describes my gender/sexuality - feminine, submissive, bi/gay. I know many of you are not submissive or bi/gay, so I can certainly understand why you'd find it less appealing, though. But it's perfect for me.
