This same topic has been posted over and over and over again.... many of the same olde, inexperienced opinions are posted in reply, declaring how it's simply not possible... yadayadayada.*If some of those people who post absolutes, like "NO" , "never" , "all" , "always" actually knew the ignorance they expose when doing so.... they wouldn't be so eager to publically opine about something they know so little about , personally!
Can a longtime relationship co-exist within The Hobby?
Yes... it has been happening for a long time... it's happening now, as I type... and will continue to forever!
As Mssppislm said. . . "Every relationship is unique, [this] is definitely not for everybody." A successful, sexually open relationship is apparently something that very few people can really grasp and understand. . . I guess that is understandable!
