Is it normal for married men to fantasize about having oral sex with men?
If you feel this real for you, then it is. It is an incredible transition to undergo. There is more and awareness out there about trans now. Read different stories and find a support network so you do not feel alone. Just live your new life. Mom will simply have to realize this with time. You can gently and lovingly confront her if she continues to refer to you as a female. Good luck!
