Ok, here’s the deal which I mentioned in another thread, do not use tuth in a setting where hookups are not immediate.
Tuth will not make a woman jump over you via the axe effect. It can happen but this is a very rare instance - do not think you are the exception and you should go out looking for that.
The more appropriate way of using tuth is at a venue where sex is actually on the mind of the people there - a night club or a bar is a place where it is ok to use it. If you use it in a library it is actually not acceptable because then you will be viewed as a dog.
Best way to test stuff out is to do some sweet spot testing.
