I believe i am leveling too fast in the game and realise that low levelplayers can win me in cock fights, any tips and strategy to level slow so i do not up my mojo too fast and focus on increasing dick size 1st?

Have you been training in the shack near the haystack? You have to train stamina at the shack, as well as improve yourself at the spa, to increase your cock fighting ability. 

Coooooool
