What If My Man Can't Satisfy Me In Bed After Marriage

Please I need to get your readers
advice concerning this.
I got dis-virgined some years back
and I have had sex with a couple of
guys. But now I have re-dedicated
my life to Christ and promised God I
would never have sex again until I
get married. Though it has really
been difficult but I have gone a year
without sex now.
Now reading all your readers mails I
am scared. What if I finally meet
someone and after getting married
to him he can't satisfy me in bed.
I need to know how I can avoid this
problem without having sex now. I
am in real need of your advice.
Help a friend please. Thanks.
