That won't work for those who pick 'virgin kink' though.
Plus imps may apply transformation potions to your sorry ass.
If you want to end up with a dragon dick or some other similar shit, be my quest.
Those who want their MCs to remain virgins aren't going to be getting much use out of the Orgasmic Level Drain Perk, are they?
You could, I suppose, adjust your settings so that none of the NPC spawns have dicks. You could also transform away your MC's genitalia to prevent any unintended deflowerings. And you can just spit out potions.
To be clear - and with apologies to those who are already familiar with this gameplan - what I advocate is the following:
1. Do the main quest at least up to meeting Brax. It's free XP.
2. Head down into Submission and get transformed into a Slime. Make sure to get transformed before entering any tiles patrolled by Imps. Leave the Slime who transformed you active, they'll be a source of Biojuice Canisters going forward.
3. Make sure you have the OLD Perk enabled. Transform away any genitals you don't want the Imps to play with.
4. Start picking fights with Imps. The transformation potion carried by the second Imp in each patrol will be an "unsliming" potion. Don't actually let them unslime you though.
5. Once you start winning the fights (assuming you bother), loot the potions from the second Imp and the weapons/cash/jewlery from the leader. Fuck all four as you please. You'll end up with a ton of cash (more than enough to set up a milking operation), a bunch of stackable loot (including a heap of unslime potions), and max out your level in pretty short order.
6. Adjust your MC's appearance as desired. then unslime. If you just threw the Imp fights to get to the fucking, you'll probably need to revisit the Slime who transformed you to beat some Biojuice out of them; if you won some or all of the fights just use one of the many unslime potions you'll have in your inventory.
Also, Imps are a great source of "futacows" for a milking operation. Free customisation and no matter how badly you treat them, you never have to feel bad about it.
