Platonic vs Romantic relationships

[Ender]

I don't really know how to say this, but I've been considering whether or not I'm gay or bi, or if my attractions to guys are purely platonic. I can notice a good-looking dude, but part of me isn't sure if I like him, want to be him, or if it's just one of those things where I just notice good-looking people. I don't imagine myself with guys in any way, nor do I imagine myself sleeping with them.

The one piece of advice I have gotten a while ago, was from a person who said (not in these words, but) the best way to know of an attraction is to experiment, essentially.

I can imagine myself with women, and pleasing a woman, but I just can't do the same with men. When I try and imagine myself with a man, it just doesn't feel right. Then again, I don't know if it's just the stereotypes around men and women that I don't like.

I feel like I answered my own question, but I do want to know if other people also experience platonic feelings for the opposite sex.
