Wife and I are 22 and have become involved in an open relationship with an close older friend of both of our families. We got married right out of high school so we dont have alot of prior experience. He is a big guy, 6-4", 230lbs and hung about 9" and thick. The issue we have is that my wife hasn't been able to fully take him yet and though he has been patient with it we can tell he is starting to get frustrated with it. We just are trying to find if there are any positions that are better for doing this than what we been doing which has just been missionary. My wife is a very small woman so thats a big part of the problems it seems.
