It's never been an issue because it's made me very secure in my personality - I'm pretty strong-willed so even though I stutter audibly, guys have never been turned off by the stutter (that I've noticed). The biggest issue is that talking in loud, crowded places has always stressed me out, so bars/parties were not my thing. Ironically, I met my fiance at a bar, and most of our early friendship happened at that bar - so - clearly with the right person, it doesn't matter at all.
