Q: What is the best base for intimacy?
A: A soft one, with good lumbar support and nothing that may result in 'carpet burns'!

Seriously though, a good tactic is to 'over product' the hair with wet-look' gel.
If it looks 'clumpy' and a bit greasy, most girls don't really want to touch it and won't be inclined to run their hands through it.

Plan B:
I HATE people touching my face (with their hands) and I make this known to anyone & everyone who cares to listen.
So, having established that, I often go on to say that my phobia extends to people touching my head and tell anecdotal stories of having to leave barbers half way through haircuts because I think I may throw-up!

The first part is true (& really only applies to strangers) the second part isn't.
I know it makes me sound crazy, but so do many other aspects of my life!
People tend to laugh, which is ok by me.
But people remember it & it works as an initial ploy to prevent wandering hands by people you may not go on to know better and can later confide in.

If all of the above fails, you can always re-enact the following scene from Saturday Night Fever, doing your best Travolta impersonation!
