That would be a bit difficult as there are several scenes scattered on many different buttons that have dialogue calling him a girl and Gomamon reaction to that specifically. Heck, it is a part of the human protagonist too as he is having fun with Goma mainly because he thinks of him as a girl at the start. I would need to rewrite dialogue and many paragraphs about it and hope not to miss anything, so I would keep it. I hope it isn't too much of a turn off for you and I do hope you will like the future updates of this game. ^^
Edit: Saw your review and I thank you for that. =D But yup, like I said, it is integral to the character. Pretty much used my own perspective there in all honesty as there was once a time where I only looked at girls in a sexual manner and not males like Gomamon, but over time my sexual orientation changed from heterosexual to cutesexual, meaning I love to lewd all the cute things too. =3 So that seeped in the making of this. I found it a fun little topic to have.
