No offense, but I am not very impressed by this surgeon's work... not very realistic, especially, in its functionality. My surgeon is far better... and hopefully, will be with me in April. This is not all that. Sorry.
Post-OP trannies do not dildo their neo-vaginas to get excited and have orgasms or whatsoever.
TS have to do this 10-15 minutes each day for a certain period of time after the surgery. It takes time before the neo-vagina is perfectly healed, so it would not "grow together" again.
At least you don't have to worry about periods with a post op if pussy is your thing but from what I read of an interview with Danielle Fox after she had her surgery, the hormone juggling act is even more of a nightmare than having monthly cycles, the mood swings are pretty scary apparently.
