Ah yes. I forget that if you devote yourself to one woman that you NEVER think about anyone else naked, but her, ever again. Ever. It will always be easy and no ones' eyes will ever stray. /sarcasm
Based on what seems to be sound advice I have gathered the following:
Have a discussion with her and avoid trying to place blame. Let her know how my 'energy' has changed and that it might be temporary (the hormone thing). Courtesy of bloodtippedrose and Bonfire.
Up the compliments, with the intent to let her know I still think she looks sexy and then show her how sexy I think she is Courtesy of Steviej.
Learn to communicate with her better via couples counseling. Courtesy of smackie9.
I'll let everyone know how it goes.
