I don't get the people who interpreted the original poster as saying she was in any way at all blaming her husband's penis size for her lack of satisfaction. She confessed it was average size but she was finding sex in the doggy position limiting. I think a couple of the blokes here were a bit quick to jump to the defensive.

LovingWife, it would be useful to know just how "plus-sized" you are. I'm categorised as obese but I don't have any size related issues with positions. However I didn't find myself having orgasm from penetration until my forties. Now that I do, it happens regardless of what position I'm in. Before that, I enjoyed sex for the intimacy and as a form of foreplay, preferring to orgasm straight afterwards from clitoral stimulation.
