This might sound ridiculous to many, but my endowment caused problems in my previous relationship, due primarily to girth. It made oral sex uncomfortable (she dislocated her jaw once, and that was the last time i ever got a bj). She would also frequently complain of vaginal pain and bleeding. To re-iterate my girth is way above average in size, and may be too large for penetration with some women, which is one issue we had.
