No, even if both of them have no physical attraction towards each other the guy will eventually be horny and start to find her attractive after spending a lot of time together. How do you think there are 7billion people on the planet??
Men and women are biologically engineered to feel sexual attraction for one another. And men are especially vulnerable to this. Men are made to spread his sperm and women to be more protective of their eggs. So guys are a lot less likely to feel only platonic emotions in a friendship with a woman.
Nope. Absolutely not. In my case, for example, all of the female friends that I've had in my life, I had an attraction to them, when we first met. Some, I was able to have relations with, while others - not so much. With them, I settled with the next best thing: friendship. And even that wasn't true friendship. It was just a way for me to bide my time, and hope there would be an opening, for me to come in and finally have the proverbial malab.
Because I'm a straight man, I'd wager any other man in a 'friendship', with women, is also of the same mindset as myself. Unless he's a battyboy.
