Does your stutter make you hesitate or second guess taking part in a conversation?

Does your stutter make you hesitate or second guess taking part in a conversation? I realized today that the reason I'm a quiet person now (I was a lively person before) is that now I don't really take part in conversations because of the fear that I start to stutter, does this happen to anyone else? I don't have a huge stuttering problem but just the risk of not being able to speak properly makes me hesitate
