I don't think a comedian should even be concerned with being cool or sexy, as soon as you do, you aren't a comedian any more. Looks are still the most important thing for women when it comes to meeting a partner. And that's fair enough, but a sense of humour is really important too. For starters, it's a great indicator of whether you are going to get on. If the first time you go on a date you don't find each other funny, there's a fundamental problem.
