well as long as its in the realms of normal, (which it is btw) generally speaking for a woman its not really the length or girth that counts its hardness! Even if you lack length or girth (which by the sounds of it you dont) learning the positions that work the best are easy enough and fun too, but no amount of positioning can compensate for lack of hardness, and as long as you and your lover are enjoying it don't worry about it. As a woman the never ending insecurities guys have about their dicks really gets irritating! sorry but it does!
Well, Libertine, I was being sarcastic, but I guess fucking horses is alright. Y'know, anything for shits and giggles. P.S. I am a virgin.
try wikipedia has a lot on the subject. there's another thread on size, like a poll (pole?) on THIS site.. wikipedia has pictures of what's called a 'micropenis'. 6.5 is above avg. appears women prefer girth to length. also women can only sexually sense up to 4" inside the vagina (per wikipedia article). HOWERVER, if you're concerned, try getting a tatoo of a ruler scaled to read 8" at the tip! hoooooo!
