Thanks for the input. I've always wondered about those pheromones - might be worth a try! Like you, I've had women on several occasions act like I was plenty desirable - if nothing else the attention helps to make me feel as if I'm not a complete loser. But I could do without any attention from other women if I could just get some attention from the woman that I'm in love with.
I agree that if I were to turn down one of my wife's "annual" advances, I'd either come across as a jerk trying to get some revenge (which I probably would be I suppose) or as being uninterested due to having an affair. Doesn't really matter - I don't think I could possibly turn her down anyway - and if I did it would probably only be if I were having an affair after having completely giving up on her. Hope it never comes to that - I don't plan on it anyway.
