Well...
Thanks all, especially warlockmaker. All of you have helped me to choose the surgeon.
After final discussion with my boy friend, who is ftm, and finally decided PAI.
Here are the brief summaries:
1) Dr. Suporn: Non penile inversion technique (developed by him), No colonvaginalplasty, High Cost (about 550,000 THB, around 125,000HKD), Outlooks Natural, Very Painful Dilation, Long Hours of Surgery (6-9 Hours), Long Recovery Time (Seems 1 yr post op to have sex), 3 star hospital for surgery, no prior hair removal, Long queue for surgery (12 months).
2) PAI: Penile inversion plus Scrotal Skin Graft Technique, has colonvaginalplasty, lower cost (about 8,500 USD), Outlooks OK, Painful Dilation (Unavoidable to dilate a wound), Shorter Hours of Surgery (3-4 hours), Shorter Recovery Time (Seems 6 months post op to have sex), 5 star hospital for surgery, no prior hair removal, Short queue for surgery (around 2 months).
As vaginas of women varies a lot, and regarding to safety (hours of dilation + recovery time) and cost effectiveness, I have chosen PAI.
I have also considered Dr. Kamol and Dr. Chettawut, I think Dr. Kamol and PAI are almost the same. Dr. Chettawut is similar to Dr. Suporn, but surgery done is his clinic and a few bad comments in the past, but the cost is really affordable (80,000 to 100,000 HKD).
But every surgery, including Dr. Suporn, has their own risk, and faults are to made by every person and surgeons.
Anyone who detected any mistakes in my summary, please kindly inform me, or correct me by replying my post.
Thank you very much for all of your help. =]
