I am one of the "I don´t share my toys" kind of guy myself but naturally as any redblooded male, the thought of a harem sure has some appeal but no I wouldn´t want that in real life for sure. Too much things that can go wrong and the potential for soo much drama that I sure don´t need.
No, I dont share my toys and neither would I share my girl with anybody. She´s all mine.
