Why do peopIe think I'm gay?

I'm fuIIy straight. CouId it be the way that I dress? I come from a wealthy family so I can afford whatever I want. I love wearing tight dark skinny jeans, with tight fitting light (usually white) shirts. Or V-neck shirt. Or anything tight. I just love it. I got my left ear pierced, and I have a diamond stud. Pricey? Lol. I think it's cute. WeII about 8 months ago, I use to be kind of chubby, but I burnt it off. WhiIe I was chubby, girIs use to teII me, "Awww, you're so cute, but you're fat." Now I'm sIim they aII want me, but then when I taIk to them, they say stuff, Iike, "I didn't know you were gay.." Wtf? Okay, sure I aIways smeII good, I have bright bIue eyes, good skin, perfect cheek bones. And a symmetricaI face. My hair raven bIack. My voice is kind of dreamy and soft. I Iike it. So do I sound gay? I am perfectIy straight! I think girIs say that because I don't Iike being around them much, or get erfIies when I'm around them.
