What if I'm afraid of commitment?
That's no good. What makes you afraid of commitment?
I don't want to be tied down with any woman.
It's quite normal to be scared of commitment and not want to be tied down with a single woman. Committing when you have doubts could result in regrets.
You're right. I will just have sex with women, no commitment needed.
I hope it goes well, at least it will be what you want. Commitment is scary and it is up to you if you want to do it or not.
