This suggestion sounds reasonable, but it might take a while for the developers to implement (due to additional complexity in menus, additional testing workload, etc).

In the meantime it may be possible for you to enjoy the current version of the game, if you're willing to do a bit of text editing:

1. Start a new game
2. Create a female character with the appropriate characteristics. If you encounter unwelcome options then just ignore them
3. Click through the introduction, tutorial, etc until you're in control of the game
4. Open the menu (ESC key) and save your game
5. Open the save file (you'll find it in the %APPDATA%\Strive for Power 2\saves folder)
6. Search for your character's name. The save file contains definitions for many different characters, so we need to jump to the correct section before we begin to make any changes.
7. Scroll up slightly; edit the has_pussy and has_womb variables to false (as shown in the screenshot below)
8. Scroll down slightly; edit the penis_type variable (human, canine, feline, equine) and penis_size variable (small, average, big)
9. You can also edit the balls_size variable (small, average, big). I neglected to include it in this example, but you'll find it by scrolling up slightly further (the variables are listed in alphabetical order)
10. Double-check the quotation marks around your edits. If you accidentally remove one of them (or add a superfluous one) then your savegame won't load correctly
11. Save the file
12. Load your edited savegame file in Strive. Your character description should now list the correct genitals
13. Apply in-game customization options (e.g. "master" vs "mistress" title, custom portrait, etc) and then play normally

Caveats:

• some scenes provide hardcoded paths for different genders. The game doesn't expect a female character to have a penis, so it won't bother to check. You'll probably miss out on a few quest-related sex scenes which involve penile penetration.
  • you can avoid this problem by starting the game as a Futa character; you can then remove the unwanted vagina via save-editing. In this case the game will still use she/her pronouns and it will allow your character to participate in penis-dependent scenes ... but the game also will label your character as intersex rather than female (which - I assume - isn't what you're asking for)
• there's an important late-game quest which can optionally be resolved by marrying your character to a female NPC ... but that option won't exist if the player character is female. You can still recruit that particular NPC (and you'll be able to use your character's penis during interactive sex scenes with recruited NPCs) but you might find this outcome to be a bit janky or discriminatory.
• the game assumes that any female character is a heterosexual cisgendered woman, which has some impact on interactive sex scenes
  
  • a female NPC will treat any interaction with your PC as lesbianism and will randomly complain about it. She'll require more persuasion (or compulsion, or foreplay) than she would if your character was a man with the exact same anatomy. Even if she's blindfolded in the middle of an, she'll recognize that your character's penis is female and she'll be more reluctant to touch it.
  • if you have satisfying sex with a female NPC then she'll eventually gain the Bisexual trait, which (if activated) will stop her from complaining about your PC being female. A female NPC can treat an encounter with your character as deviant lesbian sex (with minor in-game penalties) or she can treat it as normal sex (because she doesn't care about her partner's gender), but she'll never express a preference for lesbian sex with your character.
  • a male NPC will consider sex with your character to be totally normal. He won't make any remarks about your special anatomy, he won't complain about homosexuality, and he'll happily fellate your character or receive anal sex. YMMV as to whether that's a good thing or bad thing, in terms of role-play and immersion.
  • your character will initially be reluctant to have sex with female NPCs. Your arousal will increase more slowly than it would during a similar encounter with a male NPC. You can simply ignore this effect, or you can bypass it with the Bisexual trait (either choose it during character creation, or have sex with female NPCs until it develops spontaneously).
• I used a modded version of the game for testing, so I can't guarantee that your experience will exactly match what I've written here. But the save-editing trick should take only a few minutes, so if you're interested in the game then it's probably worth a try.

If you refuse to play a video game because you can't play as a 1:1 copy of yourself, then I'd like to think that's your problem. The point of a role-playing game isn't to stuff yourself into it, and you certainly don't get special rights to make it change to suit you. Incredibly immature, if you ask me.

Honestly, I don't think Lilith's throne like modular gender customization is going to be a thing in the near future, considering Strive Conquest's character creation is already a step down from the previous installment Strive For Power. 

In S4P, player can freely enter hair and eye color with text entry, and beastkin (well, at least fox did) had more than one fur color, and Maverik got rid of the text entry for some reason with the current limited color pallet for hair and eye color, and no fur customerization.

I was vocal back when SC first released wanting the deeper customerization back, which didn't happen. So I don't think Maverik will spend time doing modular gender customerization. But good for them if they do give us more character customerization option.
