i'm one who would wish that I could get pregnant, breast feed, and have periods. However even if modern medicine was able to do this by implanting an uterus, ovaries, and fallopian tubes in me.
I have DVT and heart attack(blood thinners) and cannot be on hormones . I have more body hair than a werewolf. I have tried electrologist(plus it would cost thousands of dollars) it worked on my face but not the rest of my body. I can understand why people would want this operation or an orchi. Due to health or monetary reasons also societal reasons that they cannot go thru with SRS. As well feeling that they do not need SRS. I also have an inoperable kidney stone which would have been broken up by a non-evasive surgery. But the doctors did not do it because of heart. Breast implants would look funny because of all my hair.
Or they may be compensating for what they cannot do.
Everyone has a right to do what they feel is best for themselves.
