I've never really thought about it before but there do seem to be some massive double standards.
Nope. There is a "double standard" because a man can "want to conceive" all he wants, he has NO RIGHT to use a woman's body for it. Zero. Therefore, if the woman doesn't want to conceive, well, then there is no "trying to conceive" for that man.
A woman can just go and find a sperm donor. No big deal, and no thousands-of-years history of coercion behind the practice.
There are anatomical differences between women and men, and it hurts women to pretend they don't exist.
We are not shocked that the threadstarter is angry because there is no history of women impregnating men by force. We know that her annoyance will have exactly as severe consequences as her annoyance with anything else her husband does or doesn't do; it will not lead to rape.
While I don't think any man should be required to have sex he doesn't want, the conondrum is, as I pointed out above, easily solved. 
The idea that partnered sex is necessary for reproduction is very outdated.
