Ok for girlfriend to hang out alone with other guys?

No way in hades is my wife/gf going to hang out alone with another dude, or a group of dudes. Many people call it trust issues, I call it cheating prevention and its just common sense. If a girl prefers hanging out with other dudes, she just likes to be the center of attention, and I would be very worried. Same goes for guys who are in a relationship, if he has hot girl friends then he's wanting to do them pure and simple. Check out Yahoo Answers and count the infinite questions that pertain to girls/guys cheating with, falling in love with, or having sex with their best guy/girl friends. There's quite a few of them, and people are still defending it. If a girl wants to hang with her guy friend then I say let her date her guy friend and vice versa.
