Why do people judge you so harshly when you haven't been in a relationship before?

[.]

Generally people are quick to jump to conclusions. It's so easy to start judging and forming an opinion of someone based on physical appearance. Maybe you seem very friendly with several girls and some people might have misunderstood you. Maybe you come across as flirting or getting too close too soon. Just some possibilities. Otherwise, it's just that people are making their own assumptions. It's common for guys to approach or talk to girls with the intention to start dating. I don't see why people would look at you negatively unless they think you're a player or someone started a rumour about you.
