Here's my analysis, constructive criticism, and suggestions:
To my ear you sound Caucasian, and you articulate/enunciate extremely well, so I can see how someone thought you might be Canadian.
You don't sound gay. You sound like you are not confident. Let me try to explain. At the beginning of the recording, you ended a sentence with an upward inflection, like a question -- this is likely why people think you are gay, because it is an inflection more common with straight women and gay men. It also implies a lack of confidence in what you are saying, and/or in yourself. In general, I sensed a lack of confidence, not just because you were approaching a woman in whom you were interested and hadn't given you the signals that she returned your interest, but I get the impression that you have a hesitant approach and are unsure of yourself, and yet also try to convince so that your need or want will be met. I sense you have an oblique approach rather than trying directly to get your needs or wants met, which is a soft approach that is an unintentional way to manipulate agreement, rather than to confidently say, "This is what I want, do you agree?" It is a pendulum swing in the other direction from being commanding and demanding, rather than what's in the middle: confident, assertive, and having self-control without trying to figure out how to control another, that is, to get them to act how you want them to act or do what you want them to do, either passively/obliquely or aggressively. Not all manipulation is intended to be aggressive and do harm, I am not implying that you have such motivations or intentions, but it is a subtle cue that people pick up on and put their guard up against, perhaps subconsciously asking, if you're not being direct, then what is it that you really want? So I think that's where some people may get the pedophile vibe from. Does that make sense?
You have a great voice and diction, you can easily retrain your inflection. I would recommend researching YouTube videos for vocal/singing breathwork, inflection training, and also postural training/exercises. When your posture is stronger, it can influence yourself confidence, as well as your voice. You speak more in your head and nose than down in your throat and chest, diaphragmatic breathwork for singing can help with that as well.
