Word she do the sex stuff with you if she was sober?

Probably not.

Just think on that for a moment will you. Just that.

'My wife has to be drunk before she will let me touch her.'

Is this a place you want to be in? Because to me it is heart breaking. That you would use her drinking to get close in that way.
Next time she is drunk and ok-ing sex the right thing to do is say no.
