I have trouble being faithful to my partners.
Why is it hard for you to stay loyal to them?
I just like to sleep around. It makes me happy.
If you want to sleep with other people, maybe you shouldn't be in monogamous relationships? It's best to be honest about your wants and expectations before entering a relationship.
Ugh, I can't deal with this bullshit. I spent 300$ on these women.
You should work on respecting women you're in a relationship with. Even if you like to have multiple partners, you can still respect them. It's going to be really hard to form new relationships if you have a history of disrespectful and dishonest behavior.
