Sitting on the guy's cock, facing eachother. A friend of mine said it was his favourite position and I can see why. Also, with two guys of similar height 69 can be great. It's not my personal favourite because I tend to be considerably smaller than whomever I'm with (by about a foot), so it's a real pretzel/taffy-stretch for me.

I've definitely over-used the top on top, legs in the air thing. Not very comfortable.
