I kind of just meant the attractiveness of women you date. Most of the time, men tend to be able to partner with women of a certain aesthetic standard but not above that standard. The implication is if they are consistently struggling to get dates with women in a certain range, they're operating outside of their line. For a person who stutters, it's very possible to go from being rejected by an unattractive woman to being pursued by a model who doesn't even pay attention to your stutter in the same day. This is obviously superficial but let's be honest, men like beautiful women. The point is really just that you shouldn't date down because of your stutter because how much a woman cares about your stutter is usually correlated with her own internal insecurities and isn't related to your attractiveness.
