Am I overreacting?

SO, I had RNY 6 months ago, lose 125, feel better than I have in my adult life.  Wife and I havent has this much sex ever.  Things are going better than ever. One day, we have people over, everyone is having fun, no problems, until me, wife and her best friend are sitting and chatting, conversation turns to the gutter, long conversation cut short, ends with wifey saying" Uhhh, I thing you need a bit bigger of a thingy to do that...."  I calmly walk away, and let her know in private I was displeased.  I guess that's an understatement to the tone of the next 24 hours, but now, her and the kids are gone to her folks. I don't plan on being here when she gets back. How am I supposed to be with someone who thinks this? Not to mention her mom, her best friend, her dad and his wife all know. Is it just me?

Since I don't know what you were talking about doing, I really don't have an opinion.  Yes, she shouldn't discuss your sex life with your mutual friends.  However, to get the type info you seem to be inquiring about, I suggest that you go to the "Sex Before and after WLS" Forum.  I know several people who post there regularly and know that, depending on how you pose your question, you'll get frank opinions.  If you are posting humorously, you'll get a humorous response.  If you let them know right from the start that this is a serious problem, they should respond in a serious manner.  Note that this is a co-ed Forum and you may get responses from both men and women.  Perhaps the women can give you some insight as to your wife's feelings.  Your wife may have questioned your ability to perform in one position as opposed to your willingness and mutual satisfaction in enjoying frequent sex.

OK, so the specific act would include us on a trampoline. Her words " Ummmm, I think you'd need to be a little bit bigger there, honey"
