I had the urge to sleep of a family member and I acted on it, now I feel bad about it.
Can you tell me more about this?
I don't think it's right and it was a bad experience.
Having sex with a family member is always a bad idea. Look elsewhere for your sexual satisfaction and stay away from your kin.
I agree, like I said I felt bad about it.
I'm glad you could see that this is morally bad. I recommend you distancing yourself from this family member. That way you don't have to worry about it happening again.
