Being monagamous, may not be our nature but, either is using a toilet. Regardless of looks, or a bigger dicks, nobody goes into a relationship with full intentions of their partner betraying them. Having looks or a bigger dick does not make you more or less monagomous. They too have a choice. We don't meet someone and tell them that they will be the only one either. They earn that right.Just think if your not monogamous you can always sleep with all those cute girls that are fun in bed but, after everything is said and done, you learned they were really lame. You did not want to fuck but, did because, you lusted for them and nothing more. That is what separates the MEN from the boys. The men know how to keep there women coming back. As for the boys they are getting everything they want NOW. Only to find they are still looking come the next day they, shall remain unfullfilled by women who are pretty lame to be. A big price to pay when you are laying in your death bed, it's your choice. Casual relationships or monogamy? Don't waste your time or the times of others. If you do not believe in love and plan on being a "player". Make it clear. Life is not forever.
