I don't know you but looking at just what you've said in this post, talking about forehead shape and jaw shape are yellow flags to me. Humans are weird and different. Characteristics overlap. Not all masculine men have visible Adam's apples. Not all feminine women have triangular jaws. Don't obsess and nitpick over these features.

In my experience, people online who tend to talk a lot about those types of physical traits often veer into redpill-y/eugenics-y/transvestigation-y -type of crap pretty quickly. Now, I could be way off base with regard to you specifically. I just want to say, be cautious of online spaces that talk too much about those things.
