Well, in this case, my waifu is a nudist. So many will have sexual thoughts about her anyway.
Hell, in that one, her pose is akin to a cat ready to pounce, while her breasts and butt are on full display, they always are with rare exception.
Myself, I find my eyes drawn to hers. Her body, though lovely, is not the only thing I love about her. Her nudism seems more an artistic depiction of her innocence and purity than simple immodesty.
That interpretation doesn't stop many from merely seeing a bimbo or a slut. I cannot control what others do or think. Nor should I if I could.
The animal matter, of course, sees what would in this world be the expression of excellent genes and health and wants to mate with it to produce healthy and strong offspring.
For the me, call it soul, spirit, or merely the wiring of the brain creating personality, such aspect sees someone for whom it would sacrifice much merely to bring a smile. Who would be a true partner, and a good mother.
Would I rather that more could see that aspect, instead of letting it be obscured by their animal lusts? Most definitely. Yet, even in comparison to those who claim to be her fans, I know that I see something more in her.
tl;dr: If that pic is sexual to you, that's your problem. I cannot control what others do or think. Nor should I if I could.
