It is true that sex isn't important for some people , for others like yourself it is a big deal hubby is just bored with perfunctory sex , he isn't excited anymore . I don't know what the answer is to put things right. I do know that badgering him ad nagging him about the lack of sex is more likely to alienate him further.
You could try a bit of reverse psychology on him by turning you back n him even when he wants to make love, but that would be like chopping off your nose to spite your face so many not be a good idea. You could buy a sex toy , and use it nighty even when hubby is in bed with you.. might spark his interest again.. other than that you may have to take a lover.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
