Have I made it obvious that I'm gay?

Not really sure how to explain this, but I'll give it a shot. I'm 16 and I'm gay but completely in the closet. My family would be completely supportive but I'm just reluctant to tell anybody and I'm not sure why.Now, to get to the reason why I posted this. I think I've accidentally made it pretty obvious(to my parents, at least). I'm attractive and popular at school, but I've never had a girlfriend which surprises people. Now not as many people know this but girls have asked me to hook up and I've made up some bullshit excuse every time(hurr I don't want to make it awkward or some crap).My dad is really a manly type of guy, and he's really damn smart so he doesn't miss much. Recently, we were out to lunch and he asked me if any girls had their eye on me and I just said probably. He asked if I had my eye on any girls and I said no, which was mistake #1. He said "Really? C'mon there must be some cute girl you're into" and I said "No Dad, stop". Mistake #2.Aside from generally avoiding the topic of girls, I am pretty much a polar opposite of my Dad in a lot of ways. He has no trouble with getting dirty and loves physical labor. I can't stand getting dirt on me or my clothes. I also try to do nice things with my hair, when my Dad always just wants a buzzcut for both of us. Additionally, we were leaving for a flight the other day and in the airport he said one of us would have to take the middle seat. I told him I refused to and he said something along the lines of "What if there was a really hot chick your age in the other seat?" and I said something like "That's irrelevant".Sorry for the wall. Basically, have I made it painfully obvious? Probably some errors in there but I typed this out on my phone and kind of just went with a stream on consciousness approach so this is probably confusing as fuck.Thanks in advance.
