<p>As Hunt said, I don’t see why sexuality couldn’t be a good essay topic. However using it as a ‘hook’ could be seen by the admissions officers as a way to avoid talking about something more boring, more common – some people might not have any substance/anything to say in there essay, so they might choose sexuality as a way out.</p>
<p>This is only my personal opinion though, I’m not saying it couldn’t work out.</p>
