Punta Cana or Puerto Plata for 4 beautiful ladies!?

Question

Help! Can't decide which to choose. Here is what we are expecting to enjoy: 1. NIGHTLIFE, 2. Activities, 3. Men and Beaches!!!!!!! 4. Locals and fun......which place can these 4 goals be accomplished best? We are in our 20's and aren't too keen on seeing a whole bunch of Kids on Old people. No offense....
