The difference being that in Strive there are only Futanari, which are females that have a penis in addition to a vagina. There are no dickgirls or traps/femboys or any other combination of sexual parts specified within the game.

However, the Arics Expansion mod adds dickgirls, which are girls with a penis instead of a vagina and differentiated from males by the size of their breasts as the game does not have any other attributes for masculine vs feminine body type. I don't keep track of all the minute differences in names, but traps and femboys both sound appropriate.
