Hello, I have lifted all of the curses on the items I have equipped and also removed the anal underwear thingy but free cock options are still blocked out. Idk what to do 

Seems you had an encounter with Alma the Warlock and got permanent curse at some point. If that's the case, Hiro is officially a girl, forever.

Or if you didn't, you have a chastity cage equipped in chastity cage slot.

Sounds like someone had too much beastiality sex, and visited the strangest merchant ever.

And / or got a little too curious for their own good.

Only way to remove that. ( if not the warlock curse )

Is a) modding your customization in the beginning ( key ), or purchasing one ( stores have them about 100gp ).
