When a man hires an MD to chop his dick off so he can play pretend-"woman" you 1. Understand the patient is mentally ill from the get go and 2. Put that MD in prison for willful and grotesque malpractice. We don't amputate body parts to cure mental illness. This isn't 7,000 BC.
You are one sick and misinformed puppy. We don't know that EITHER of these women had genital reassignment surgery. Over 70% of transgenders never do - some because there are dangers, some due to cost, but MOST because it's just not a priority.
There has been no scientifically identified "mental illness" associated with being transgender. The suicide rates are high because of a-holes such as yourself.
Grow up - and leave people the hell alone. It's none of your damn business how they identify or what they do in the bedroom.
