How do you build trust?  Over time - with practice.  Aside from being honest and faithful, building trust has to do with how you react to things.  If you always react negatively, she will have fear, not trust.  If you always react positively, her fear will evaporate and trust will grow.  With sexuality, our most personal and intimate area, fear of rejection is huge.  If you always react in a positive way in other areas of your lives and conversations, then she is more likely to trust you won't reject her when she reveals her innermost desires to you.

So - how do you react?  One indicator of a relationship's health is how the couple argues.  You want to move from throwing dishes and breaking stuff (in the extreme) to sitting down and talking things through - ending with understanding and a hug and kiss.

So begin with lowering your defenses.  If something can be taken two ways, take it in the most positive way.  Always give her the benefit of the doubt.  Always assume she is on your side and that you are together. 

There will be conflict in any relationship.  It is healthy when both parties feel safe when they express themselves, so listen to each other and try to figure out what's really going on.  Arguments are seldom about the thing being discussed - but more often about a list of perceived injustices.  So flush them out into the open.  Talk about them, resolve them - one at a time.  If you cannot do this yourselves, get some help.

• Never lie to each other
• Never be secretive

One thing you can do is make agreements. For example: if you are more than (insert mutually agreed to time frame here) minutes late, call as a courtesy out of respect - not out of fear or monitored obligation.  Remember: you are both adults and do not need to be monitored - but you do need to be courteous out of mutual respect and love.

• Never lie to others

If your wife sees you lie to others, she will wonder if you lie to her.  You have to BE trustworthy.  Then she will start to trust you.

• Always do what you promise to do
• Be dependable

I am project challenged.  But I have made it a point to get things done that I promise to do.  And so my wife's trust for me grows - and so does her passion.

• Take the high road

Sometimes you have to "man-up" and just let go of being right and tell her you really did not intend to hurt her feelings.  (If you did intend to hurt her feelings, then you are missing the whole point - get some assistance.)  Tell her you are on her side and on the same team.  Swallow your pride and ego and just care for her feelings and she will appreciate it.  For the most part, women are not logical - they are emotional - so don't try to fix and prove - you may win but you will lose much more.  Be a man and take one for the team.
