Neekitacd The feeling which you have is one common and primary thing with every person suffering from gender dysphoria. I have got married at your age, I thought the feelings were only rare and I have control of my mind. I didn't knew I was wrong. The feelings started coming more regularly and with brutal force after 12 years of my married life with two kids. Then I realised what injustice I put my wife to and what i am doing to my kids right now. I completely understand your situation.
My suggestion, like all others, is not to marry. You are not only ruining your life, but you are going to damage the life of your wife. Once she gets married to you and in future you want to divorce her for your transition, she has no one to go to. Society will wreck hell upon her. I request you to not marry because you are going to destroy another person's life who is going to be a life partner to you. If you still choose to marry with the dysphoria and the feelings of being a woman of your dreams, you are committing a terrible mistake. If you are bowing down for the pressure which your family is putting you to, that doesn't justify your action to the girl whom you are going to marry. No one can compensate the damage which the girl will have to suffer once she realises you are not a man.
PLEASE REFRAIN FROM MARRIAGE IF YOU CAN!!!!
