Shyness and approach anxiety are usually stemming from other fears and anxieties than sexual. But this title nevertheless will help you in a way where you might override those because of your new found comfort and increased desire to take action regardless(sexual energy). The confidence boosts and resilience.
But if you want to go deeper into your shyness and anxiety another title would probably process faster in those areas than this one, like true social, DD and primal. Those are focused on the social, but anything with focus on status and confidence will also help. Of course healing titles as well.
I suggest you explore where this fear really comes from, for best subliminal for you.
