No it isn't. It's based on trust, respect for each other and love. Why would you share the person that you love? You might as well stay single if you are going to sleep around with other people.
every relationship is based on trust respect and love.
monogomy, prohibiting your loved one from loving others, and vice versa, is a relationship designed to make the two who partake feel special, better than everyone else. your partner neither needs nor wants
anyone else but you.
depends on what you mean by single. very few people want to live alone, spend their life by their lonesome. we all want a partner, someone or people to spend our life with, to come home to, wake up with. but that doesnt mean you have to isolate your sexual being and sexual love from other people. its not necessary to isolate your partner either.
i like monogomy, i like feeling special, but i do so knowing full well that such a relationship is based on posessiveness, jealousy, insecurity, and immaturity.
a non possessive, unjealous, secure, and mature person would not want to isolate themself or their partner from other people, in any way shape or form. they would be happy to see their partner forming other loving relationships, and take pride in being with someone that others wanted to sex.
