Re: sex life after hysterectomy
I feel so badly for you right now, because I know you'd like to fix this immediately! There is nothing more frustrating than wanting sex from your partner when they're not in the mood. I had a loveless marriage, and he never wanted sex, either...so I completely understand your frustration.
Okay, you mentioned culture, and I forgot we weren't talking about the States here. Since HRT is out of the question, do you have access to Marriage Counseling? She could have something going on much deeper...even deeper than hormone issues. She might want to look into seeing a Neurologist. Sex Drive is everything to do with neural impulses, so that might be a good place to start.
I admire you for not wanting to find your sex elsewhere. I also admire the fact you won't give up on the marriage, too. There are only so many times one can say "hang in there", because that's horribly frustrating!
So, to answer your question: yes, in normal situations, the libido does return. Maybe she just needs to understand sex won't hurt anymore...that's the reason she had her hysterectomy. If she can just realize it's okay, and it's not going to hurt, that would be a huge hurdle for you both!
