Beachcomber - thank you, very helpful post.
This documentary has sparked a lot of discussion in my household. I was talking to DP this morning about the bit where MH just starts having sex with Felicity and it brought up all sorts of questions... things we discussed around:
He didn't gain explicit consent from her before doing it, therefore surely it is rape. But was her using the lubricant on him implied consent? (leaving aside the coercion/money aspects/her vulnerability for now).
About how you could see from her face how she really felt and that she really didn't know how the hell to stop it or say no or get out of there. Reminded me a lot of myself when I was 16 with 24 year old men, the not knowing what the hell to do and how to get out of the situation 
About how in relationships you wouldnt get explicit consent each time you had sex but you would obviously get implied consent, I suppose I mean you kiss you partner, he kisses you back, things progress, at each stage you would assume that if your partner responds then they are consenting. Not quite sure why we started talking about this but it followed on from talking about explicit consent I think.
It was obvious that the nasty pimp took her to MH to get her to see everything else as 'normal' almost and at least 'better than that'.
I think it also shocked me how low Felicity's self esteem was that she would listen to MH's rather obvious tricks to try to get her to carry on and actually fall for it. His 'logic' was along the lines of that I use on my 6 year old 'I bet you can't get dressed in 2 minutes' type stuff. The fact that she actually 'broke' under it showed me that she was obviously in a very difficult place emotionally, and just the sort of person they prey on 
Sorry just rambling. Documentary has raised a lot of questions/thoughts with me.
