Men, does he think I am desperate because of this? 10 points?

Basically, I didn't look twice at him all semester long. I thought either he was taken or out of my league because secretly, he is the sexiest thing (in my opinion) I have ever seen in my life. Then, he starts hitting on me (VERY aggressively) out of nowhere (after talking to me for a couple hours at a school event). Obviously I was excited (tried to hide it) and gave in. He gets a lot of girls, true. But he told all his friends about me and how much he really liked me. I turned down a few dates with him on purpose, but....Does it seem desperate that I didn't resist?
