Q: I have been a resident in a foreign country for about 10 years. 2 years ago I met a woman who is completely feminine in nature. As time passed our relationship grew stronger. I wanted her to marry me and convert to Islam. She showed interest in doing so but the real problem is that she was born male by gender, and at the age of 21 she had her gender change operation and removed all the male sexual organs with female body parts. Now she is a women in all ways. There is no going back for her. She is supposed to be a women for the rest of her life. My question is, is there a possibility that a Muslim can still marry her given her circumstances , otherwise we know that to have gay/sexual relations with a man is a despicable sin. Please suggest me what to do.
