I am a 21 yr old female newly-wed to a 39 yr old ...

Hi,
That an unusual situation..... If the sex is great why is it so rare ?.  No wonder it bothers you and no wonder that you seek for a solution.  Let me ask you sveral questions (no offence please, some of the questions might be too straight):
1.  Does he thinks that your sex is great ?
2.  Would you define your relations as good ? (That means:
     Trust + Openess + Communication + Respect). 
3.  Are you (both) in good mood ?
4.  Do you (both) enjoy the company of each others (Do
     you have good time being together) ? 
5.  Could he have someone else ?
6.  Could he be AC / DC ?  or gay ? 
7.  Is he attracted to you ?   
After you get a good idea what are the reasons to his strange behaviour you'll have to finf the proper solution.   At this point what I would suggest is set a meeting with a marriage consultant.  Don't ignor it !.
Best regards,

P.S.  Don't underestimate the frequency after 10 years of 
        marriage......  I know a nice couple that after 40 years
        they still have sex for 1-2 a week !!!! (no joke !). 
       can asuure you its more than 1-2 a month....

Something definitely does not sound right here. I would suggest sitting down with you husband and discussing your concerns. If he's not willing to talk openly, seek out professional help as there is something not right about the whole situation. Good luck!

Yes there is something wrong, a good relationship is usually accompanied with a healthy sex life.Something is happening with your husband , don't blame yourself for it, it might be stress related. You must demand honesty, the key for your continuation in trust. If you feel this way from the beginning then you might need to take some serious stands.

HI,

Does your husband have high blood presure?  Or any other medical problems?  The reason I ask is because the medication could be a factor in his interest in sex.  Also, you are only 21 and although I would never suggest that you leave your marriage, you are sooooo young.  I would give your marriage an honest errort to fix things, ie.. counsling, heart to heart, just anything in you power to save it.  Otherwise, you are much to young to stay in a marriage where you are not happy!!!  Good luck girl!!

It sounds like you need a divorce.  If you are indeed young and attractive don't waste your youth on someone who prefers his own actions instead of "real" sex.  You don't deserve that.  Move on and stop making his problem your own.

Hi Auxiecap ,  I agree something is wrong in your marriage , How does your husband explain to you his  " Not Tonight's " and his picking Porn and masturbation  over making love to you  ???   You two need to seek professional help , this is not the behavior of a happy loving husband , you need to find out what is going on with your husband .
