My standarts are way too high.

Hello!I've been in this subreddit for a while, and I post here every once in a while, but that's not the topic here.My problem is my standarts, I think they are too high, but I can't help it. I've met a lot of guys, but I have never dated anyone (Which is why I'm 19 and single). I could start a lot of relationships, but I refused every single time cause a single flaw made me deny them, and I hate myself for that.I'll give you some examples for you to understand what I mean by that:A long time ago, I met a guy I really liked physically and the way he was thinking. He was a cool guy, a fun guy, but I refused him cause he had the "gay accent" and he was quite "whore-ish" if you can call it like that (aka, his actions were not the best).Met another guy, but I refused him cause he was saying some really annoying or cringy things every once in a while. I guess he was too immature for my taste.And lastly, I met a guy that I also liked by his looks, but he was shorter than me, like... 15 cm's shorter or something. Also his breath stank quite often (But maybe that's cause he's smoking).So yeah, these are some examples of what I mean by my standarts. These little things are automatically making me refuse them.I'm sure the most common comments would be "Lower your standarts" but it's easier said than done, I've been trying for a long time to do that.Maybe someone has a familiar story that they would like to share? I'm kinda mad on myself for being like this to the nice guys.
