In a world where we're fighting to get non-compete clauses removed from employment contracts, medieval, mate control obsessed fuckers like you think you deserve to restrict another independent human with a non-compete clause for something as frivolous as sex. You are several times problematic than a cheater. As long as a child isn't being affected, unrelated adults have no obligation to compromise with their personal freedom for each other just because they have sexual relations with each other. Having sex with someone doesn't give you any right to their personal life. If I don't have to "break up" with a current friend before making a new friend or ask permission from my old friends before making new friends, I am definitely not demeaning myself in that matter for a mere sex partner.
Y'all seem to forget that the concept of mating partnership only exists for the purpose of co-parenting with the perks of mate controlling to improve your reproductive chances, sure, but child rearing is the main purpose. Legalized domestic partnership was created for reproductive partners because the resulting children needed that, not because the adults need it. Adults are self-sufficient and already have a family and a wider social circle of friends to care for them, if needed. If you think that just because you have some affection for someone, you should get to own them, then you'd better get married to your friends before you even think of marrying a sex partner.
Then why not be open about it and ask for an open / polyamorous relationship? Being in any kind of personal relationship means that you care about the other person and don't want to hurt them or betray them. So, if you know that you don't want to be bound to just one person, but your partner has another view, then talk about it and find a compromise or break up. Why hurt the person you are supposed to care about?
Usually you are most intimate with your romantic partner and usually people don't trust several people to be intimate enough. (I am not talking about sex, but sharing all sides of you, including the bad ones, expose yourself to be very vulnerable.)
If you don't have such a boundary, then good for you, but respect others boundaries, especially your partner's.
And don't mix up work with personal life. Of course there are people that are very loyal to their companies and companies that are good to their employees, but usually companies exploit their employees as much as possible and see them just as numbers. And in return employees work their to gain something and they don't expose themselves to their companies like they would do in their private life.
I really detest cheaters! They are one of the worst kinds of people in this world!
As if cheating is not enough, they tell their gay partner (directly or indirectly): you can't give me kids... !!!!!!
So those kids are responsible for your damn mistakes? They are responsible for you hurting innocent people?
Argh!!!!!! These people make me puke!!!!! No one gives anyone the right to cheat! There are people who don't mind or accept their partner having multiple partners, but that's not cheating, that's a different story!!!!
But cheating, rape, human trafficking, etc. are the worst!!!!!!!
