I think it depends on the individual comfort levels within each relationship. For me, I had a lot of guy friends long before I ever got married -- most of my friends, actually, because I really don't get along with other females very well. That said, my husband has been cheated on before, and out of respect for him I am very careful to keep my actions above question...which includes not hanging out with my guy friends without him. He has never asked me not to visit with them by myself, but he appreciates that I don't and affords the same courtesy to me -- any time spent with friends of the opposite gender, we also spend with each other. The only males I do hang out with when he's not around are my cousin and my stepson (who is only a few years younger than me), and occasionally my husband's best friend (who is learning disabled and who is certainly not a concern to my husband). He doesn't question how trustworthy I am, but I feel that it's better to never give a reason to doubt...and, quite frankly, there's no other male I enjoy spending time with more than him, and I want to make sure he knows it.
