Confusion

So I recently have found out i have become extremely attracted to Transwomen. I have no idea how any of this works I am or was a straight male 29 and married. Do I try to explore this in secret, talk to my wife or just repress the feelings? I am 100% sure this would be a deal breaker for her and I value our relationship more than my sexual needs but it makes sense why I have lost almost all sex drive for her. Im just extremely confused on the situation any advice appreciated.
