If you force her, then it is no wonder she does not enjoy sex wit you. You are a monster and should be locked up.
Married couples with mismatched libidos is such a huge problem. The rate of sexless marriages are as high as 30% so I defenitely believe that this something that should be discussed before marriage. Sex shouldn't be the end all be all in a relationship but being denied a need (be it sexually, emotionally, physically) will cause tension, resentment and would it all be worth that. Try to fix this problem now before it becomes engrained in your marriage. Therapy with a sex therapist, date nights, maybe a vacation away..Did something happen that caused her to create distance?
When it comes to sex, some people just aren't as interested as others.
Like SeriousSam said, it's the kind of thing that needs to be discussed... preferably, prior to marriage.
As for using "force," heatherlynn22 is quite correct in that "forcing" would constitute rape, regardless of marital status. Also, I would think that a caring and loving person would want their partner to give of themselves willingly; not, forcibly!
Anyway, I think that you both could benefit from marriage counseling or sex therapy to adequately address this issue.
Why does she not want sex? Have you talked to her? Did you have sex before the marriage?
even though you're married if you force her to have sex....you are raping her. and that is illegal. if she wanted to she could report you to the police and you could be thrown in jail. DO NOT FORCE HER TO HAVE SEX. not only is it illegal she'll start to hate you and REALLY not want to have sex with you. i know if my husband forced me to have sex i would be filing for divorce the next day.
if you're so miserable because she won't have sex than divorce her. ask her seek professional help. i.e. a therapist. there could be an underlying problem on why she doesn't want to have sex. perhaps she was sexually abused as a child and is uncomfortable with it. you forcing her will only make it worse.
