Keep playing, good things come to those that wait. Seriously, if you're just looking to get laid or have fap material, this might not be the game for you.
From the Guide:
Holiday Island has a relationship and stats system for you and your ravishing fellow island guests. The quality of your relationships is the key to your progress. The game is constantly updating the parameters for traits such as: love, affection, anger, strength, charm and endurance. There are no wrong choices! The game is designed in a way that you cannot mess it up completely. There is always a way to recover and come back from poor decisions.
Initially the game can be a bit of a grind as you try to raise your stats and the stats of the women on the island. Just like in real life you will get hungry, horny, drunk and need to sleep! Winning over the hearts of all of these busty knockouts takes work!
