Are Girls stronger than boys

I made a big mistake last week. I'm 14 and my girlfriend is one month younger than me and about 40 lbs less than me. We had a project for school together so i invited her to my house to work on it. My parents weren't home and she challenged me to a wrestling match(we are both jocks). I accepted not knowing her true streingth. This little blond was not only smart and sexy, she was pretty damn strong. She put moves on me before I even was ready and had me in a choke hold quickly. Before I knew it, we were on the ground and my head was between her sexy legs. I didn't mind of course, I like strong girls. Anyway, she could've pinned me within a minute but decided to go a little longer and show me moves I didn't even think she knew. Afterwards I had the biggest headache. She ended up being more worried than me though, she thought that i wouldn't want a girl who was stronger but that wasn't so. We've wrestled twice since then and she's kicked my $%!@ every time.
