What if they physically can't fill that sexual role due to distance or some other circumstance? But if you do cheat...i think you have to be honest or else make damn sure that doesn't become a pattern because then in my opinion if you have sidepieces you dont love her.
This is a good point. I think in some cases being long distance for an extended period of time can cause one to forget about being in love with someone. That love fades to the background and the selfish need to fulfill one's own desires over everything can take over.
HOWEVER I would also argue that if you are TRULY in love with someone that either
A) Long distance would never break the bond. That whatever sexual sacrifice you need to make will be worth it in the long run.
or
B) If it's an extremely long period of time, you would relocate to where that person is if possible to maintain that physical connection even if it includes sacrificing/compromising some of your career goals, life goals, and overall preferences.
It's a tricky situation, but I will say the dudes in here talking about "OF COURSE YOU CAN STILL BE IN LOVE WITH HER AND CHEAT...BUT DON'T GET CAUGHT BRO!" are sounding real silly. Like I said...big difference between loving someone and being IN LOVE.
You can love someone and grow to be in love with them for sure, but the minute you start shoving your dikk in other women's vaginas you are firmly in the "I really like her", "I love her but I'm not in love with her", or the "She's cool to be around, she's cute, and her vagina is aight" zone, NOT the "I'm in love with her zone."
