Physical transformation is in my opinion no way possible, gender change would only be possible through talking it through with a psychologist and trained professionals who will assess your situation before deciding whether you are a suitable candidate for surgery.
Glamour spells are only illusion and in my opinion one should be happy and proud of who you are regardless of the so called flaws they might think they have, no one is perfect!
Now to the spells part!
I suggest using common sense when looking at the spells on here and not believing everything you read.
If a spell also tells you to ingest anything use common sense also ie: some herbs are very dangerous if ingested.
Well the thing that annoys me most about these gender spells is that people are actually meaning to change their sex. Gender is how you feel and pretty easy to change your sex is what's going on down below. You can be male with a female gender and female with a male gender.
If you are wanting to change your sex desperately I'd reccomend surgery.
If it's your gender then it wont be too hard and you don't need magick really.
Acting as a member of the opposite sex doesn't mean gender change: a male is more than a haircut and a female is more than make up. And surgery doesn't give the real thing, it's just mimicking. AFAIK, only magick could do the trick. If you say it can't, so why is there a spell about it?
I got in touch with Aworosasa. He wrote to me that he could cast a spell to change gender (and clothing) at will (I couldn't even be wounded when changed, he wrote) but he failed to give me convincing proofs: only testimonials on his own site or from members of this forum which have never contributed before they wrote to me how a great spellcaster he is. And he asks for $200 to buy the stuff he needs for casting the spell.
He has offered his services to other members here, but it seems that none of them can testify on his behalf.
