There are some, but the adult content is not the main focus of the game.
'
Some'?
That's far too modest!
There are LOTs of spicy scenes in your game. I think the number, frequency and flavor is great. There are sexy little rewards (scenes, unlockables, extras) everywhere for progressing the story and side events.
Great work/reward ratio in my eyes. I think there is a big chance - even if playing this for the adult content mostly - to be perfectly happy with what people get. You have achieved a great pace and balance.
My point:
I think you can and SHOULD confidently claim that you have a LOT to offer in terms of adult content. Quantity AND quality. Even if that MIGHT not be the main focus of the game for you. Otherwise I'd see the risk that with being too modest here, people might give it a pass, thinking there is not enough for them - even though they might potentially greatly enjoy the amount of content. That'd be sad and almost... a case of false advertising to your own disadvantage. While actually delivering but claimimg you don't.
That's paradox and could undermine your success. (And I'd like to see you guys succeed very much.)
Just my 2 cent.
