I'm completely heterosexual but sometimes I enjoy looking at a well built naked man who is not in a pornographic pose. I don't think of it in terms of a sexualized thing. I just look at his picture or live body and think "wow, he put in some gym time". I've known straight women that have liked looking at the Playboy models for similar reasons.
I'm quite happy to look at pics of naked men Matt but, if I'm honest, my eyes go straight to the cock and balls. Just for comparison purposes of course! Unless it's a really nice one!!
For something you call non sexual, your phrasing and illustrative comments are quite sexual. Maybe you need to sit with these feelings.
Iam primarily straight. I like the naked body. So, yes I do like looking a mans naked body, as well as a woman’s body
I am bisexual, I do enjoy the sight of naked guys. In fact, I had come across one particular pic that featured a guy who is in his fully erected state, it's so erotic i saved it in my laptop just in case,
