Problem is, even if they have golden heart, they cannot accept a session for free, because afterwards, hundreds will ask the same!
I had a similar situation than you. From 2001 till 2010 i dreamed to make a session with such a girl, but i could'nt do it.
I was married, so no money no possibillities! Only fake fight with my wife. But as she was not really trained and half of my weigth, i had to break a lot. Later on she started with Karate and before we got separated she got the brown belt. But also here only fake fight. Even if she had the same stats like Antscha, she hat maybe 20% more bodyfat and lesser hard muscles. So even then the fight where fake.
I hope your condition will getting better soon.
