For anybody who likes to preserve purity for as long as possible (no penetration): It works right up until the fourth Pillar boss, where difficulty picks up and you're pretty much forced to prostitute yourself to get the money to buy new armor and weapons. Unless you REALLY like grinding.
Surprisingly high amount of H scenes though. I approve. Good and fun little game
I actually just cleared the game as a virgin. I wouldn't say I really grinded either, I just completely explored all the maps, and almost never escaped from fights, I was level 33 when I fought the last boss, dunno if that's a normal level.
The only unfair part was the last dungeon, there I ran away from all the fights(escape chance is 100% in this game), got the best ring and cape(I think?) from the chests and fought the last boss. And killling the last boss requires a fair amount of luck, you basically just keep using the 100 tp attack and hope it becomes a critical and one shots the boss, In my case I seem to win 1 out of 4-5 fights.
In the end nothing special at all happened for beating the game as virgin as far as I can tell, so it was just a waste of time I think. No new game plus or anything and the ending was pretty lame too I dunno if it's same or different than non-virgin end though since it's the first end I've got yet. However I've noticed that in the room before last boss fight there is a locked door leading to some stairs, that door and stairs never became accessible to me, maybe it's a non-virgin thing?
Edit: I also just cleared the game with sexually liberal status and ending was the same.
