Is it very important to communicate what you really want?
Do you have the right to set segxwal limits and to communicate them?
is it unfeminine to EXPRESS AN INTEREST IN HAVING SEX? or Uncool to make your lack of interst clear?
Everything is acceptable if the two can agree and within the matrimonial covenant.
Better to be diplomatic about sex: what goes and what's a no-no shouldn't be hard and fast rules unless of course they violate Ur person or are contrary to God's ordinaces.
Sex knows no gender till conception takes place. There's nothing wrong with a man or woman expressing themselves with their partners and both sexes have libidos and the urge to satisfy or be satisfied is not gender biased.
With the right person in the right relationship, sex can be a wonderful thing.
Of course if U built the relationship on sex in the first place U shouldn't expect that communication of other forms on other levels will be so smooth or welcome.
Intimacy should be built one simple block after the other.
