Reyna is clearly very straight, hence her crush on both Jason and Percy, so she's bisexual(at the most), but that's never even been hinted at, and she surely would've told Nico(considering she found out about him on accident through the Bellona kid power-transfer thing).

Rachel is clearly very straight, hence her sorta-crush on Percy, so she's  bisexual(at the most), but that's never even been hinted at, and she surely would've mentioned it to Percy, whom she gave up to become oracle.

And on the subject of Oracle, you seem to forget Rachel is unable to form any romantic connections and must remain an eternal maiden, hence why she had to give up Percy, hence why May Castellan(who was clearly not a maiden-she'd had a baby in fact) could not become Oracle.
