Given a choice, I like it trimmed close. Been with shaved completely and never, ever thought "man... Only if she had some stubble..."
Do what you are comfortable with. I like trimmed cause I think completely shaved can look a little adolescent. Clean and neat, I think, is best.
But, as I said, he IS NOT going to stop mid stride and say... "Wait!... Wait!... The Homeowners Association CLEARLY states in their charter that all lawns are to be trimmed to 2.5 inches missy! No more, no less!"
Really... You are overthinking it. Girls are so cute that way. You work so damn hard to make us happy.
The guy might have showered, used soap if he remembered... Maybe brushed his teeth or ate a tic-tac.
