@The O.P, the level of attraction that a female feels for a guy depends on a lot of factors such as how a man presents himself. Guys who seem confident are usually more attractive to women then guys who seem insecure and unsure of themselves.

It has nothing to do with being an extrovert or being an introvert. Guys who are to extroverted can be very annoying to some women as you can see by the responses you got. Some outgoing guys can even look like players, or they can even make themselves look shallow or conceited by trying to be the center of attention to often.

Try to work on becoming more confident. Even if you're feeling insecure, try to hide it and try to act more confident. Most women would rather be around a confident guy even if he can be arrogant at times than an introverted guy who makes it clear that he is insecure and full of self doubt.

You obviously have some things to be proud of like the fact that you have a professional job, a degree, so try to focus on what's good about you instead of dwelling on your inadequacies. Introverts tend to be better listeners, so use that to your advantage and ask women about themselves. Most people love to talk about themselves. It'll take the pressure off you to talk-

Most people don't want to be around anyone who seems hostile, angry, insecure, depressed, unhappy, negative, or those who tend to complain a lot. Trust me on that. I used to come across as being that way w/o meaning to in the past. So I try to keep my self doubts and insecurities more to myself these days, at least in person. On here I seem like a hot mess to some probably, lol.

Being called an introvert is NOT a criticism btw. I'm one apparently. Only stupid people will assume that you're boring w/o getting to know you better. I don't consider myself to be boring usually. I usually have a lot to say, but I'm selective in who I talk to. If other people don't want to talk to me because I'm quiet, then fine, I don't want to talk to anyone who'll judge me that quickly anyways.

Try talking to more people and in time you'll become more socially confident. I'm in my 40's, but omg, when I was in my 20's, I had such bad anxiety, that I couldn't even talk to most people, even the clerks at the grocery store! The fact that I managed to even get jobs and get married was a miracle! So there's hope for you too-

Just don't give up. Try making more eye contact and small talk with strangers. If they don't respond to you the way that you expect them to, then don't take it personally. Try not to take things to personally. Things aren't always about you doing or saying the wrong thing. Sometimes people like us are so hard on ourselves, that we naturally tend to assume the worst in other people. Sometimes people can just be rude, unfriendly, having a bad day, busy, tired, etc....

So if you say hi to someone for example and they don't respond, don't assume that person doesn't like you or whatever. If they do that all the time, then maybe they don't, but then don't take things personally. You tried to be nice, and they're not even trying to be polite, so eff them, lol. Don't say hi to them again.

Remember that there will always be jerks in this world. Try not to worry so much about what other people think about you. The more you worry about what other people think, the more it'll show, and that tends to repel most people. Not sure why that is, it just does. It also tends to attract the worst kind of people out there. Stop caring so much about what other people think and just be yourself.
