Whatsoever resides with you, that keeps you from doing things you (think you) want, is something you can seek to address on your part. A stutter is such a thing. There are many factors that go into flirting, courtship, etc. (as with all things in life, really), and there's no need to boil the logic down to "I stutter, so I can't". You can. You've just accepted that your stutter keeps you from doing it. So, don't accept that. It's a change in perspective, we might say.
