As a woman if a dude I slept with or dated before liked a bunch of suggestive pictures of mine, I would DEFINITELY think he was interested in me and wanted to sleep with me again.

What if he's indiscriminately liking all photos? Do people really think linking a photo is anything beyond showing support for someone?

Most of the things I like I do so in a supportive fashion, not because I literally like everything I press, but maybe that's weird of me?

I feel like the both of you(yourself and OP) are projecting the reasons you like photos onto the rest of the world. What if you like a photo of a female friend? Does that mean you'd like to sleep with her, or is it only supportive in that case and sexual in other cases?
