Okay, so recently I've been seeing a lot of people calling yiptrip out for the sexuality on her profile changing on occasion. This is not some defensive journal, and I'm not white-knighting Samm. I can understand disliking her, because I've been there before, trust me. Hell, I still have a problem with the way that she behaves at times, and the things that she says in anger. However, that is no excuse to pick at every little thing that she does, especially if you don't even know what you're talking about.
Sexuality is not a concrete, set-in-stone character trait. It's fluid, because it's based upon emotions, and everybody knows that over times feeling change and vary. 90% of you, even those that consider themselves homosexual, identified as "straight" at one point or another. Then, you gradually began to discover more and more definitions that fit you better than the one you were using to define yourself, and that was okay! Nobody had any problem at all with that.
You are not limited to one sexuality. There is no guidebook labelled "how to be -insert sexuality here-". There aren't any rules to follow, and sometimes one simple word is not enough to describe the complexity that is human attraction. If Samm identifies as a demisexual lesbian, that's a-okay with me, and if you think it's not, then you simply don't understand the logistics behind sexual preference. Simple as that.
"Demisexual lesbian" is basically just another term for "female-leaning demisexual". This means that you are attracted to females (i.e. lesbian), but that you experience a lack of sexual attraction toward any person unless they become deeply emotionally or romantically connected with a specific person (i.e. demisexual). In this case, it is perfectly fine to use the two terms, because they do not contradict each other. Instead, they work together to describe one's sexuality on a deeper level.
This goes for everyone. If there's a young child on the internet, claiming to be bisexual, or a lesbian, or even asexual, then there is nothing wrong with that. Chances are, they recently discovered the meaning behind the word, and decided that they thought that fit them best! You still have your impressionable kids who follow the crowd like sheep, but honestly, that's fine too. The point is that it will change over time, and judging somebody based on whether or not they like dick is just ridiculous. Everybody deserves a chance to discover themselves.
I firmly believe that you are not born with a pre-determined sexuality. Instead, we are born with the mental capabilities to address our stages of arousal and to determine based off of that who we are attracted to. No, you do not have to draw straws in order to pick your sexuality. No, you do not have to narrow it down to one term. No, you do not have to break down if you're a "lesbian" and you are attracted to a man. Just settle on what you feel.
Lower your standards, not everybody has to get their sexuality right on the first try. Things change.
