No...no...no. "Blind faith" would have been if you had no prior experience of him, men or living life at all. Even your human instincts... the stuff we're born with that makes us go yummy when we see a firm and muscular ass removes you from the ability to claim that you said "yes" based on nothing but "blind faith".
Let's sort out the terminology. "Faith" is about measuring things and drawing conclusions from it. There's Kierkegaardian faith, (the so called "leap to faith") where you accept that there's holes in our ability to gather evidence about some things and you simply need to fill in the holes yourself to get a meaningful picture. But that still isn't blind faith. It is also different from the leap of faith, (as defined by Thomas Kuhn) which is when we've measured enough times with the same result to assume that it will always behave the same way. This is the type of faith who people who believe in scientific theories hold.
Both these are different from "hope" which is wishful thinking.
"Blind faith" is when we spend no time reflecting about anything, and rather try to beat any kind of thinking or reason out of the equation at all... probably because we subconsciously know that we're not going to like the result. Keeping ourselves intentionally in the dark because we're is fighting to keep a delusion intact. Blind faith is nothing anybody would want to be proud of ever. If you do, you haven't understood the terminology. To be blunt, it's a bit like tattooing the word "retard" in your forehead and sporting it proudly. Just don't. Please.
"Belief" covers all three definitions of "faith".
Maybe it was more like this: You squeezed that firm soldier ass and hoped that it would stay rock hard for a long while longer, and from this inferred that you were very much in love with him and couldn't care less about reason or measuring any damn thing! Could this have been a more accurate description of it? I doubt faith entered into it anywhere. It doesn't really fit.
Mr Fixit: I'm fucking proud of my intellectual jargon.
