I've been with my fiancé for three years and we have always had a good sex life - twice a day on average and sexts/loving texts in between. I feel he has always been more up for it than me and was always stood to attention as it were.
We have always had a tempestuous relationship too but that hasnt seemed to dampen desire.
In the last few weeks he hasn't initiated sex and has said he is too tired on a number of occasions When I have and I have felt rejected and feel insecure that he is no longer attracted to me. We discussed it and he says he is feeing tired and doesn't know why his libido has diminished. He makes the effort and if I turn him on he will have sex with me but it isn't as passionate as it was and I feel guilty, like I'm making him have sex and I don't want that.
I feel really sad as I can't see a reason why things have changed (i.e. We have both felt tired or under stress in the last three years but always had a strong sexual connection regardless). I think he is no longer attracted to me even though for the last month we have been getting on better than ever. He wants to get married soon as do I but I can't help having this nagging doubt that the relationship is in decline if he doesn't want to have sex as much anymore and feel that he doesn't love me. Outside of the bedroom he can't do enough for me but he is a considerate person in general. He is kind, loving and a beautiful soul.
I have tried to research why men stop wanting to have sex with their partners and he doesn't have medication, depression etc and we are both in our 30s. The desire he had for me seems to have literally dropped off and I can't see any reason. What should I do? I'm doubting whether we should go ahead with the wedding as I feel so sad about this issue.
