Your wifes response was simular to mine when my H does these king of things. My H always feel it is based on I don't want him to touch me. But really it is how he touches me. And how in pursued I feel. Had you have walked up behind your wife and rubbed her upper back or upper arms first while telling her how hot you thought she was you may not have gotten the same response from her. When my H and I have had no contact and he immediately makes contact in a sexual nature. It is a automatic turn off for me. It is not loving in nature it is pure he wants sex in my mind. I feel used.
And her response yes you will. Is true you will. My H says this often also. Two days later he is at it again. And BF says it is us woman that say something today but don't mean it tomorrow!
I hope your wifes stomach is located in a normal spot. I seem to be a freak of nature who's stomach seems to reside right along there pelvic line. Or is it my H just does not know anatomy well
