What makes a woman “masculine” and how can she change her ways?

She’s educated and has a high earning skilled job, can hold her own in a conversation with many people, can lead an independent life but wants to be with a man… how does she become more “feminine” in a relationship?

Never realized truly that me being “outspoken” was deterring my dating options with “masculine” men and I’m at a point where I need whatever intervention is available.

I know my insecurities can get triggered when speaking to some men, and that I have a hard time giving up control or trusting what they say if the relationship is new. I think these are largely due to fear however and not to do with being “masculine”.
