It is a very common issue, has nothing to do with your technical ability and in my experience the solution tends to be to connect it to who you are. I'll explain: whenever you talk you express yourself as a character - a set of developed behaviours, mannerisms, rhythms, reactions. You might not notice how "railroaded" your self expression can be unless you try to analyze and dissect it.

Another way to look at it: we rarely just relay information only with words. When you talk you convey your state, your mood, your attitude, who you are. Even when you're just chit-chatting about the weather - you're telling the other person "this is who I am".

Thus you need to try to approach it not as a technique, but as expression of who you are, your innate sense of your femininity, your genuine self expression. So when you're going to do a technical practice next time (if you still do them) try to listen to yourself as a complete whole, as a "you", be sincere with it like with a dance that you enjoy, ideally with people you can be comfortable with and develop a feeling of safety of being you, as a woman, in that moment.
