A question about goo's tentacle sex scene

[yrsa9425]

I noticed a bit of a strange thing: when the PC has sex with celise on the starship, you will loses the virgin no matter which option is chosen, in Zheng shi have sex with Roz will loses your virgin too, but you doesn't lose the virginity when PC comes to having sex with Nova, also not losing virginity when having sex for the first time while teaching with celise, and when having sex with Nihara in the coc didn't let PC lose a virgin too, But they all make love the same way, use their goo tentacle to penetrate PC.

This confuses me a bit: why they are the same race Galotian, but we having sex with different Galotian not necessarily losing the virginity?

One Nova isn't strictly speaking a Galo she's a Grey Goo with the one of her scenes being a masterbation aid not true penetration sex. For the rest of those cases it's most likely down to author or coder preference.
