Sharing Partner

Recently, I observed people of both sex are more relax in sharing another partner. Recently, a friend of mine was alone since his girl friend gone on official tour. Another friend offered his girlfriend for few nights. His girlfriend was with us having dinner together. She straight away acknowledged idea and she was with my friend for few nights.

After researching, I guess lot of young generation swap partners when ever they are horny. That means, it is no more taboo and partners dont feel possessive. The good thing is, there is no possessive attitude from any of the sex and pure sex become need. Secondly, secret extra marriage affairs dont have any room, since everything is open and no vindicative attitude, fights, disillusions, depression. Everything is open and it is more pure. Both partners know what other partner is doing and that increases trust and confidence on each other. Any one experienced this and what is your thought on this subject???
