I had this thought a couple times and wanted to bring it to the table. I've seen several threads about whether or not porn plays a factoring role in helping someone figure out their sexuality; but what about others opinions? Imagine you are in a place with no one who knows you, just people with similar generic interests, like a convention. Someone stops to chat with you about a shared interest, somewhere into the conversation they determine you are a lesbian/gay/etc... how does this affect your opinion of yourself? Does it change, reaffirm, or shock you? I was recently approached by some people on a dating website after trying out the 'bisexual tab' for a three-way relationship. After chatting a bit with the guy, he claimed it wouldn't work because i'm a lesbian and they never messaged again. Some weeks later, I chatted back and forth with a guy who, again, accused me of being lesbian and never wrote back. I admit to being puzzled by this phenomenon. Should this influence me? Should I reanalyze myself? Do other's opinions about you shape who you are?
Sometimes other's opinions can give an unusual insight into things we never consider, but it's best to simply acknowledge how you act before you change. Perhaps you do give off certain "lesbian" tendencies, but don't let it change the way you act if it's a part of who you are. There's still the possibility you just met stereotyping idiots, and that maybe soon you'll meet someone who is actually comfortable with who you are.
If I'm under the impression that having a moustache makes someone a rapist or that having an interest in books makes them a virgin, am I right just because some other moron agrees with me?
