Ehh, my stutter has been through different periods of how bad it is throughout the years. I started to speak to girls in middle school, at this time my stutter was kind of bad most of the time so my anxiety of "how do I start a conversation" and "I'll stutter and mess it all up" were at maximum levels but it went fine, something that really helped me (even to this day) was to start with any small talk (i.e. math class was pretty boring today, but we're finally free!), that helped to "grease the groove" and continue to speak about other things. During highschool my stutter got somewhat better and my anxiety of speaking to girls in a flirty manner went away, so even if I stuttered, most of the times they didn't really cared or just thought I had a brain fart. When I started college my stutter got pretty bad for some time but that reduced anxiety when talking to girls and knowing that I was about to block made me find strategies to substitute words and just keep it fluent, again, when I stuttered they either did not care or just made a "huh?" face and moved on. My "funny nature" and an ability to be able to speak about mostly anything did not make it that hard, but don't get me wrong, some girls did get weirded out, but the vast majority didn't and don't care, I got in different relationships with no problems. Like other posts have said, if the other person likes you it won't matter, our personalities have nothing to do with it, so if she rejects you for stuttering, well good ridance honestly.
