It's not in the design of the game to give girls to easily. If you think you already have a hard time being where you are without any drop... you are in for one hell of a ride. I completed all scrolls there were at that point (the second to last one of world 4) before I got one drop and I'm still trying to get all drops from Dark Lord to this day as do many others.
As for experience, you can always switch to a troll which is within level range to receive experience. I might also point out that, if you have lvl 1 girls, you can get loads of exp by forming a party with them to collect as much orgasms as possible before you win the battle. More orgasms = more exp
Mojo lacking might be frustrating but, as a tip, don't bother to much with it right now. It will take months of dedicated mojo-farming to get that far and, aside from the obvious ranking, it doesn't give much.
Just stick to the troll farming, albeit with a lvl 1 party if you can, and pray to RNGesus for a girl because let me tell you, it's worth it
