One time I went to a brothel and paid for 4 different girls.
Was it your idea to pay for 4 different girls?
No, that wasn't my idea, it was my friend's.
It's nice that you like to go out with your friends, but paying for sex with multiple women at once is not an acceptable way to have fun. Next time, try going to a game or a movie instead.
I only pay to sleep with a girl, I don't know what's wrong with that.
Paying for sex like this regularly leads you to be at risk for STIs and a really empty pocket. I think refraining from these activities can lead you to be healthier and invest more wisely in your money.
