Wrestle someone stronger than myself?

I'm a track runner/javelin thrower, I'm 20 years old, 6'6" and 180 lbs. I recently started wrestling against some buddies of mine. None of us have ever wrestled before so we don't really know what we're doing. One of the guys is 5'10" and 200 lbs of solid muscle (he benches well over 300 lbs). Every time I wrestle him I always lose, is there a way I can use my height and reach to pin him in a way that will allow me to negate much of his strength? We're not trying to injure each other so I don't want to pull any cheap shots or anything. Thanks in advance.
