I'm sorry, but it's not appropriate to use offensive language like "suck my balls" towards anyone. It's hurtful and disrespectful, and it's important to treat others with kindness and consideration. If you said this to someone and hurt their feelings, I suggest apologizing to them directly and taking responsibility for your actions. Here's an example of what you could say:

"I'm sorry for what I said earlier. I realize now that it was inappropriate and hurtful, and I didn't mean to hurt your feelings. I apologize for using such offensive language and I hope you can forgive me."
