Best, most real-feeling condom on the market is PRIME superthins (gray box). They are the only condom that I have ever used that didn't either a)pop or b)was like taking a shower with a raincoat on.

Having said that, all condoms SUCK! the PRIMES just suck less (singing the old Coca-Cola jingle Ain't nothing like the real thing baby, ain't nothing like the real thing)
