Over the course of my life, I've cheated on 3 girls and I feel no remorse.
You seriously cheated on 3 different girls? Why would you do that?
It was what I wanted to do.
You shouldn't cheat on anyone, even if it's what you want to do. If you want to have casual sex, then you should either be single or be in an open relationship with someone who is comfortable with that.
An individual can do anything until they get caught.
Rather than waiting to get caught, why not just be honest about what you are looking for when looking for a partner? There are people who are ok with the idea of having an open relationship. That way, you can have sex with other people without hurting your partner.
