It's a relatively new vaccine, this commonly happens for a few reasons:

1. They start with a cautious roll out to the highest lifetime risk population (teenage girls in this case)

2. They may be limited by vaccine stocks as it does take time to build up product. There's an entire world to vaccinate, billions of doses needed

3. They need time to prove that it will be useful to give to other populations - in this case, adults

There's no conspiracy here, you had to push to get it because you were going against the existing recommendations, which were reasonable. Not because of your gender.

Those recommendations have likely changed recently because when I went in for shots last month (male, 40s) they immediately recommended that me and my partner both get it.
