Twin primes are prime numbers which differ by exactly 2. The twin prime conjecture states that there are infinitely many twin primes—that is, there are infinitely many pairs of prime numbers (p, q), where p < q, such that q − p = 2.
The first few twin primes are (3, 5), (5, 7), (11, 13), (17, 19), (29, 31), (41, 43), ...
The twinprime conjecture is an important open question in number theory.
when one man and another man have sexual intercourse with a woman by scissoring each other in a way that their penises are parallel to the other's. Then the woman proceeds to ride both penises; either both in the vagina or one in each hole.
