do spaces like that exist? maybe some corners of tumblr. I think this is a common experience for young boys having their first crushes.

Grown feminist men are supposed to have figured out how to relate to women as other people so they're not paralyzed by trying to talk to them. Even without explicit theory you learn not to put women on pedestals. Posting this kind of stuff would look like softboi performative harmlessness (usually a lie), and it would be weird to try and combine that with an open expression of desire anyway. If you are a left-of-center man who's attracted to women, the cultural norm is to shut up about it because the misogynists are saying gross shit in locker rooms and you don't want to do that. There's not really space for healthy/nonthreatening desire yet.

Grown anti-feminist men are supposed to have learned a specific script of heterosexuality (PUA, etc) to follow, where they are in control of the interaction and set the terms of it. For these men, open expression of harmlessness or being disarmed by a woman's gaze or whatever makes you a cuck and is therefore verboten.
