The reason he can get people to sleep with him is because he's famous. Not to mention, 102% of the time on Jersey Shore, girls were worlds under the influence. It's really not that hard to get a girl drunk, put her on TV, and have a guy try to get in her pants. Honestly, only an idiot could fail at that. It has nothing to do with his "muscles" (which, by the way, are pretty much nonexistent). He's a poser, which makes you one too.
