Were Hotaru and Chibiusa implied to a be couple in crystal?

Why are Chibiusa and Hotaru portrayed as naked together in the opening of the third season of crystal? Also since Hotaru says to her in Crystal and the manga that they were destined to meet by fate even though they are girls does that imply them to be lesbians or bisexual?

I always took it as lost souls that just understood each other

I don't get it why nudity, especially in this case, gets interpreted as something sexuality-related. in this case they are shown as god(dess) created them (us) and it stands for purity and vulnerability.
